Reconstruction was a band formed by John Kahn to occupy him while Jerry Garcia, his long-time musical collaborator, was busy with The Grateful Dead. The band's original guitar player was Jerry Miller, best-known for performing with Moby Grape. Garcia, who wanted to play in a jazz band, replaced Miller in 1979. Reconstruction performed only for an eight-month period in 1979. The band's first performance was January 30, 1979 at the Keystone in Berkeley, California. Its last performance was on September 22, 1979, at the Keystone in Palo Alto, California.
