Crosby, Nash

As with the duo's self-titled debut from 1972, Wind on the Water wouldn't exist had David Crosby and Graham Nash actually been able to get along with Stephen Stills and Neil Young. But apparently, drugs and egos made that darn near impossible, so the former two often struck out on their own, and made some really good music in the process. Crosby, in particular, was on fire, penning such jazzy soundscapes as "Bittersweet" and the album's closing medley about such eco-friendly issues as the extinction of whales.
