310

310 are two old friends from New York: Joseph Dierker (currently resident in Seattle) and Tim Donovan (engineer at some of NYC's top studios; has worked with A Tribe Called Quest, Wu Tang, etc). The duo work by relaying tapes of new work across the continent, each building on the other's previous work.
Andrew Sigler collaborated (as Fire/fly) on several 310 tracks. Just before the Recessional album he joined officially.
