Today, as Eastman's music is being brought into the spotlight by Wild Up and others, he's celebrated as an experimental visionary who brandished his own provocative way of getting the listener to think about sound and context. For this performance, the band plays a 15-minute arrangement of a longer piece from 1973 called Stay On It. The music is nothing less than an exuberant house party unto itself, infectious and revelatory. To perform Eastman's works, Rountree says, can be transformational. "They're the kind of pieces you breathe in as a musician, and they do their work on you," he explains. "And when you breathe them out again, you're breathing not only the piece but also a different version of yourself." SET LIST Stay On It
