The album is the first to feature guitarist Joe Walsh, who would later achieve success as a solo artist and with the Eagles.

Of the eleven tracks featured, three are covers — Buffalo Springfield's "Bluebird", "Lost Woman" by the Yardbirds, and "Stop" by Jerry Ragovoy and Mort Shuman, recorded a year earlier by Howard Tate, as well as a version by Al Kooper and Mike Bloomfield for the Super Session album (albeit without vocals).

In the locked groove at the end of side 1 of the LP version of the album (which is normally silent on most phonograph records), the spoken phrase "Turn me over" repeats in a loop, while the locked groove at the end of side 2 repeats the phrase "Play me again".

A 'producers note' in the gatefold warns listeners not to spoil these endings to friends who have turntables with automatic return.

These messages are removed from CD pressings, but are included on the 8-Track & cassette tape versions.
