Among the warehouses just west of Biscayne Boulevard and north of the Design District lives birdman (a.k.a. Sean Gould). Since graduating in 1987 from Clemson University with an English degree, the six-foot-four blond-haired Gould has been honing the art of what he calls "urban pioneering." What this amounts to: moving into a blighted or barren city landscape and launching a homegrown rock club. The latest incarnation is the musical compound he now inhabits at 6720 NE Fourth Ave. He calls it birdneststudio. Since December 1999 Gould has been manning the mixing board and playing MC during live recording sessions of local rock bands at the warehouse. Birdneststudio is at once a recording facility, a rehearsal space, a live venue, and a home. Gould got the impresario bug while working with old-school production and engineering legend Tom Dowd, whom he met during a 1995 recording project in Miami. With area rock venues in short supply, birdman's base of operations keeps the embers of local talent smoldering.
