Musicians are the same as baseball players in that regard. Once a musician has proved that he or she can be great, it doesn't matter how many bad records come out afterward; the next record or tour could be great once again. Three of the four members of Crosby, Stills, Nash & Young are obviously of Hall of Fame caliber by any standard, and the fourth did enough great work to at least merit consideration. Just because most of them haven't recorded anything worthwhile since about 1971 is no reason to write them off just yet.
By the time he was in his mid-20s, former Byrd David Crosby had been a major part of some of the greatest records of the '60s. Stephen Stills and Neil Young were staking their own claims for immortality across Los Angeles in Buffalo Springfield. Meanwhile, Graham Nash was a major player in England's the Hollies. Three albums into their joint career, the foursome had pretty much run out of steam. Only Neil Young would continue to make brilliant music over the next 30 years.
Two years ago, CSNY reunited for what by all reports was a fantastic tour, featuring songs from all periods of their respective and joint careers. Now they're ready to do it again, and we're ready to see these veterans prove what put them on the musical all-star team in the first place.
