Borborygmus first rumbled onto the San Diego music scene at the dawn of the millenium as the performing unit of the newly formed Trummerflora collective. The ensemble's energetic live performances can be heard on "No Stars Please" (2001 Accretions). The Wire described it as "collective improvising: a pool of players immersed in the unfolding of a continuous present, egos submerged in the sound stream. The stream's currents tug towards free jazz, the extremities of rock, the 20th century chamber avant garde and electroacoustic strangeness." Though active only for about a year, the group's rumbling effects can be heard on many of Trummerflora's subsequent releases. Now after nearly five years, Borborygmus rears its multitudinous head once again to cast forth the gurgles and growls from the belly of the musical underground.
