Released in summer 1967 as Atco 33-224/mono, SD 33-224/stereo, it consists entirely of half-speed covers and three short original instrumental compositions.

[1][2] Parts of the original stereo LP were actually mixed in mono, including the entire track "You Keep Me Hangin' On".

Allmusic's Paul Collins retrospectively rated Vanilla Fudge four out of five stars some time in the 2000s.

He stated that "nobody could accuse Vanilla Fudge of bad taste in their repertoire" and that most of the tracks "share a common structure of a disjointed warm-up jam, a Hammond-heavy dirge of harmonized vocals at the center, and a final flat-out jam."

"[3] Side 1 of the album ends with: "The following is a series of high-frequency tones..." CD reissues have a modified track listing for the tracks on side 2 of the LP: The text in all uppercase letters in the CD reissue track listing spells out "STRAWBERRYFIELDS".
