I first discovered Jennifer Warnes' take of "First we take Manhatten" on a promotional CD from one of the World's leading microphone manufacturers, whose mics had been used to capture the incredibly tight drum sound on this album. It's a spectacular recording which compliments, rather than detracting from, a set of superb musical performances.
Cohen himself is reported to have listened to some of the instrumental takes, before Warnes added her voice, and to have been incredulous that it would work. Apparently he was later rather stunned by the result. He sings in duet with Warnes on "Joan of Arc".
Altogether an excellent interpretation of Cohen's work, a superb range of musical styles, and a CD for the Hi-Fi Buff to die for. In fact, that's the only real caveat - it sounds SO good on decent equipment, that it may lead the buyer down the hi-fi upgrade path!
