According to Lillian Roxon's Rock Encyclopedia, the album was released in December 1969.[3] Reviewing for The Village Voice the following June, Robert Christgau gave the album a "B" grade and wrote: "There ought to be hundreds of groups like this one—hard, competent, slightly commercial—but there probably aren't more than 20. This is not especially original, but it's good, and I'll bet they're a stone happy gas live."[2]AllMusic's Mark Deming later gave it three-and-a-half out of five stars and appraised it in comparison to the band's harder previous records, calling it "a fun album that generates an impressive groove ... a more laid-back and relaxed effort, but it still rocks with a strong and steady roll."[1]
The 2007 Japanese mini-LP sleeve reissue of Blue Cheer contains the mono non-LP single "All Night Long" (Kellogg) b/w "Fortunes" (Peterson) along with the single versions of "Fool" and "Ain't That the Way" as bonus tracks.
