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. Might Could is on hiatus, as are the Elton John and ELP cover bands that included Tim and some other Sonus folk. Tim and Luis also play together in The Devil’s Staircase, a band who makes music based on physics and mathematics.
