CPR are also awesome. I have both of their albums, and they're kinda like CSN but with keyboards, which is sweet.
Is that a gimmick cover band or something? playing on the fact that CSN are really old now?
No, it was a serious band, and a pretty good one, too. Crosby, Pevar, and Raymond. Jeff Pevar is a guitarist, and James Raymond is David Crosby's son.
If I remember correctly, James was given up for adoption, as Crosby and the boy's mother (whose name I forget) were very young and not in a position to raise a child of their own. After reaching adulthood, Raymond looked into who has parents were, and his father turned out to be David Crosby. They got together, and Raymond seems to have inherited Crosby's musical talent, but plays keyboards rather than guitar. They jammed a bit, and decided to put a band together. CPR made two albums before breaking up, but Raymond plays keys for CSN and Crosby-Nash when they tour.
Their albums are both great. Harmonies similar to CSN, music has a similar sound, but different.
