Here's a favorite of ours. Magma's "Otis"--performed in 1981 and 2007. Christian Vander's ultimate scat ballad...a bittersweet limit experience in sound...No holds barred insanity in the name of avant garde free jazz interpretation. Vander may have gotten older and beefier and bad hair-ier...but his mania has only purified like a fine wine. Merci Boucoup!
