Andy Tillotson - Drums, Guitar and Vocals

Luis Nasser - Bass

I'm the founder and last remaining member of the original band that formed in Mexico City under the name Radio Silence in the early 90's. I'm living proof that sleep is wrong, and have the scars to prove it sucks to be right. Overall, I'm a reasonably well-adjusted, sometimes heavily self-medicated, caffeinated and insane inmate on this gravitational prison, orbiting at 30 km/s round the Sun. Just like you, but with a much more magnificent torso and a family that kicks ass. Afraid of heights, so I bass to keep me safe and low. Just a human. Being. Can you paradigm?

Rich Poston - Guitar, Keyboards and Vocals

Guitarist Rich Poston started his first original band in 1988. The four piece Psychotic Romance released a four song cassette and the band later resurfaced as a three piece called Requiem.

In the late 1990s, Rich worked in many cover bands, most notably, Mary Ann and the Professors. He kept his love for progressive rock alive by performing with the Genesis tribute band, Cinema and the Frank Zappa influenced Dr. Bizarro and the Disgustos.

In 2004, Rich took another stab at original music with the mainstream rock band, 4 Letter Words and released the CD “4LW.” Soon after, he became involved with the Jethro Tull tribute, Silver Pipe (as a keyboardist!) where he started working with Steve Royce and Luis Nasser.

Now Rich performs with three original progressive rock bands: Department of Revenge, Origin of Animal, and of course, Sonus Umbra.

Roey Ben-Yoseph - Lead and Backing Vocals, Percussion

Roey Ben-Yoseph is a singer, drummer and songwriter who joined Sonus Umbra in 2012 as lead singer and percussionist to help complete Winter Soulstice. He is also the lead singer of Chicago area prog rock tribute bands Grand Parade (Genesis) and Fanfare (ELP), which is where Roey got to know Luis and Tim. Since the late 80's, Roey has sung and/or played drums in a number of bands covering many different musical styles, including folk rock, power pop, glam metal, hard rock, world music and prog rock. As long as the music is good, nothing else matters.

Steve Royce - Flute, Keyboards, Vocals and Holophonics

Steve played his first note on a Flute back in 1973 as a freshman in high school. He quickly learned that in order to get his chance to jam on Flute, he needed to play some other instrument to fill in the gaps (sax in Jazz band, rhythm guitar, bass or keys in rock bands, you get the idea). He received a degree in music theory and composition from UICC (now UIC) where he developed a love for orchestration and arranging. Playing in various original and cover bands over the years, good friend Dale Stubitsch urged him to finally start a Jethro Tull cover band in 2006. With the help of Dale and Rich Poston, Silver Pipe was born. Over the years, the lineups changed and eventually included Luis Nasser, Tim McCaskey and Brian Harris. As Luis began recruiting to record Winter Soulstice, Steve joined in to add Flute, backing vocals, arrangements and general energetic ‘tude, becoming absorbed in this creative collective of musicians he’s honored to call friends.

Tim McCaskey - Guitar and Vocals

Tim played a mix of fingerstyle acoustic guitar and whatever other prog or metal he could pick up in his youth.  He met Andy and Luis in graduate school at the University of Maryland, where they all got physics degrees.  Andy and Tim formed the acoustic instrumental group Might Could, of which Luis also became a member.  Tim is still active in Might Could and also plays guitars with Fanfare, an Emerson, Lake, and Palmer tribute act led by Brian Harris.

Bill Harrison - Drums and Percussion

Bill's drumming was influenced in college by Genesis, Yes, Gentle Giant, and 801 among others. After a lengthy break, he got back into thd drums in 1999 with Genesis tribute Grand Parade. That led him to meeting various musicians in the Chicago prog community, which led to drumming in a variety of bands before joining Sonus Umbra In 2016.

Sonus Umbra

The past is but prologue.
Back in the early 90's, three science students from the national university in Mexico City, Andres Aullet, Ricardo Gómez and Luis Nasser got together to form a band called RADIO SILENCE. From 1991 to 1994, the band played on, gaining a large cult following and a reputation for intense, unpredictable live performances. Inevitably, the band broke up, but the music and the meme lingered on.

In 1995, Nasser and Gómez moved to the East Coast of the USA under the pretense of pursuing scientific doctoral degrees, but all they really wanted was to find other players and continue what RADIO SILENCE had started. Two fruitless years later the search was abandoned and the two drifted apart; Nasser sulked in his apartment and alternated between writing music and working on his dissertation, while Gomez jammed and played with a number of different bands, ranging from punk rock to Spanish baroque troupes (which included the stretchy pants and full peacock garb).

In 1997, Nasser auditioned for a Baltimore-based band KURGAN'S BANE, led by guitarist Pete Laramee and his brother, drummer Jeff Laramee; a crisp, crunchy hard rock band of exceptional musicianship that had parted ways with their bassist and were on the eve of recording their debut album "Search from Sea to Sea". These sessions resulted in a a good friendship between Nasser and John Grant of Secret Sound studios in Baltimore, and the later discovery of a vast network of websites promoting underground prog rock made him curious to find out what the internet crowd might think of the material performed by RADIO SILENCE, back in the smoggy, boozy daze of Mexico City.

Nasser and Grant set upon the task of embellishing a demo of original material recorded on 8-track tascam tape machine for release. During the course of this project, Nasser invited Gómez and Aullet back to the fold, and the end result was a disc called "Laughter In The Dark" which, to everyone's astonishment, earned rave reviews, sold out in months, and inked the band a record deal with the now defunct indie label "Moonchild Records".

Nasser's musical chemistry with Jeff Laramee made his addition to the band as a full member in 1998 inevitable, and certain unfortunate legalities forced the band to re-name itself as SONUS UMBRA, which in pig latin roughly means "Shadows Made Of Sound". Since then, they have released three more critically acclaimed albums: "Snapshots From Limbo" in 2000, "Spiritual Vertigo" in 2003 and "Digging For Zeros" in 2005.

SONUS UMBRA went on indefinite hiatus due to the stress of continued existence in spite of vast geographical limitations: Gómez returned to Mexico City in 2000 where he is professor of mathematics at the National University. Nasser is a professor of physics at Columbia, Chicago and remains committed to recording and performing with his main band MIGHT COULD. Aullet is coding furiously in Sandy Point Idaho and Laramee remained steadfast in Baltimore, drumming with Pete Laramee and running a warehouse with his unusual gifts as both stunt fork-lift driver and a master of depraved English.

Working intermittently with his close MIGHT COULD bandmate Andy Tillotson, he and Nasser wrote music that eventually became "Winter Soulstice". The process began in late 2008 and concluded in April, 2013. A new incarnation of the band was formed with some of the most accomplished veteran musicians of the Chicago rock music scene, and is ready to release the first new album in 8 years and begin promoting the material live.In the slightly twisted words of Neil Peart:
    Shadows on the road behind.
    Shadows on the road ahead.
    Nothing can stop us now.
Come hear us live, form your own opinion.
Band Interests
To seek the null beyond the half ley line.
Tasty beer.
