the most unusual song on the album, a 1930s style tune written and sung by Spence. It was given a spoken introduction from Arthur Godfrey and cut onto the LP record at 78 RPM with added scratchy sound effects to give it an authentic period effect. Grape Jam has been criticized for its rather loose and mostly improvised performances which contrast sharply with the heavily produced material on Wow. However Grape Jam is also notable in that it features guest appearances on piano by Al Kooper and Mike Bloomfield. This studio album was recorded in New York City in January and February 1968. Skip Spence plays guitar on "Never" and piano on "Boysenberry Jam". Peter Lewis does not appear on this album. "The Lake" is a strange combination of poetry submitted by a fan (Michael Hayworth, the winner of a KFRC San Francisco songwriting contest) and avant-garde psychedelic Musique concrète sound effects somewhat like side four of Freak Out! or "Revolution 9". The opening track "Never" is the best known song and has often been cited as the source for Led Zeppelin's song "Since I've Been Loving You", the opening lyrics, bluesy arrangement and some melodic elements are virtually identical. The album was the inspiration for a number of other studio "jam" albums during the late 1960s and early 1970s. Later examples of this trend included Al Kooper's Super Session and the 3rd LP of George Harrison's All Things Must Pass.

Christgau went further on Grape Jam, referring to it as "hippie self-indulgence" and "wooden groove instrumentals". Rob Hughes of Louder Sound, meanwhile, has referred to Wow as "a disjointed affair," but "hardly a disaster," highlighting "Bitter Wind," the "creepily-hypnotic Rose Colored Eyes," the "funked-up Murder In My Heart For The Judge" and "Spence’s clap of dirty thunder, Motorcycle Irene" as "classic Grape". A retrospective review of Wow by Mark Deming of AllMusic is mostly positive, arguing that it is "a far more ambitious album" than the band’s debut, that it "has plenty of strengths despite the excess gingerbread" and that while it lacks the "rev-it-up
