Jeff Cosgrove oversees a very delicate kind of chaos on "Alternating Current." It's the drummer's latest album - a largely improvisational three-song set the Washington native recorded with bassist William Parker and pianist Matthew Shipp, two jazz heroes who know how to anchor their elasticity with heavy concentration.
Cosgrove has performed on the local jazz circuit with everyone from the late Butch Warren to the up-and-coming Kris Funn. Before that, he studied under Andrew Cyrille, the avant-garde drummer who has shared the bandstand with Shipp and Parker. And so the album's title track is dedicated to Cyrille, the man who brought these three together, and they do him proud with playing that's thoughtful and taut.
But the album's highlights come during "Bridges of Tomorrow," a nearly 40-minute expedition where Cosgrove's drumming doesn't provide the music with an engine so much as a lighthouse. When the dialogue between Shipp's and Parker's fingertips picks up speed, the drummer makes his cymbals shimmer, as if casting a warm, bright light.
