Stills first album is a masterpiece, equal to Young's Harvest, although quite different. It reveals the different influences each one of them brought to Buffalo Springfield and later CSN&Y. But unlike Young's steady 70ies output, Still's albums were unequal, some times good, but most of the times unfocused.
But Crosby collaborations with Nash had their high moments:
take the money and run,
Carry me
And Crosby's LP:"if I could remember my name" reveals its power to the patient people.
Nash's "Songs for beginners" and "Wild tales" are solid good!
