Here is an excerpt From NPR: Weather Report: 'Heavy Weather':
SPELLMAN: It's hard to pick out a sample from a composition like "Birdland" because it's all of a piece. There are no big solos, but a series of conversations between the electronic and acoustic instruments, with vocal sounds, and handclaps thrown in. Joe Zawinul is especially interesting with a gorgeous palette of keyboard effects, all perfectly placed so that the music is loaded with surprise.
I don't know if I have a favorite group or musical performer but in a list of favorites, Manhattan Transfer and Weather Report would be near the top.
