Tapes of this club gig by guitarist Jorma Kaukonen and bassist Jack Casady, on stripped-down folk-blues holiday from Jefferson Airplane, became their 1970 debut (with harp man Will Scarlett) as Hot Tuna. This CD of earthy, gently swinging outtakes has acoustic spins on later electric-Tuna covers ("Candy Man," "Keep On Truckin' ") and a long spell of intricate fingerpicking and dancing electric bass in Kaukonen's "Sea Child."

“IRM”

Fashioned to mimic the sound of a magnetic resonance imaging or MRI, "IRM" (the French designation for the brain scan) grew out of Gainsbourg’s love of the sound of the clickety-clack of medical machinery. The IRM album project also marked the fulfillment of two goals for the singer: to document a traumatic experience, and to record an album with Beck. Though her co-creator and producer didn’t necessarily know the details of her water-skiing accident and resulting cerebral hemorrhage (which lead to the IRM of the song's title), he somehow knew how to handle the material. "Beck had a way of guessing what I was thinking and feeling without me telling him," said Gainsbourg. "We never discussed these things explicitly."
