Classically trained double bassist and songwriter Mike Silverman has toured and recorded since the mid-‘90s as That 1 Guy, using as his primary instrument something he has dubbed the Magic Pipe, a homemade contraption that features two long, connected metal pipes, each with a standup bass string attached. The Pipe also features a line of MIDI triggers that allow Silberman to control a bank of computerized sounds, as well as accompanying video projections—all while plucking, bowing and strumming his heart out. But that’s not all: There’s also something called the Magic Boot, which Silverman uses to maintain each song’s rhythm. The result is surprisingly fluid and funky.
