The LPs reissued on this two-fer were The Spirit of '67, originally released in November 1966, and Revolution!, originally released in August 1967. The two albums mark a dividing point in the career of Paul Revere and the Raiders: in between their releases, the band split, with Revere and singer Mark Lindsay hiring a new group of Raiders. The hits "Kicks," "Good Thing," and "The Great Airplane Strike" anchored The Spirit of '67; with much in common with the twangy guitar rock sound common to 1966, some of the experimental eclecticism that would lead to the elaborate productions of the psychedelic era was also apparent in songs like "Oh! To Be a Man" and "Undecided Man." It took an unprecedented nine months to craft Revolution!, though the Raiders did issue three singles in the interim; the Rolling Stones-ish "Him or Me: What's It Gonna Be?" and the whimsical "I Had a Dream" anchored Revolution! and defined its stylistic range. An ambitious album that made extensive use of studio gimmickry (and mimicry), there wasn't much substance to the experimentation of Revolution!, and the loss of the Raiders' lineup of 1965-1967 robbed the music of the forcefulness of the group's initial hits.
