Buffalo Springfield (1966)
A solid debut album that ranges from British-invasion pop to rock to the sort of country-rock that band members will develop further in their next bands (Crosby, Stills, Nash and Young, Poco). Still's "For What It's Worth" (added to the album after its initial release) is the most familiar track, but Young's contributions, such as "Nowadays Clancy Can't Even Sing," are significant.
Buffalo Springfield Again (1967)
Even though the group was already falling apart, this is their best album. Again Stills contributed the album's biggest hit, "Bluebird." But Neil Young was turning into Neil Young with songs like "Mr. Soul" and "Broken Arrow."
