Best known for their hit “Whiter Shade of Pale” (1967), the UK-based prog rock band Procol Harum “developed a really new sound with two keyboards (piano and Hammond organ) and a guitarist extraordinaire called Robin Trower who was greatly influenced by Jimi Hendrix,” (ProgArchive). “They quickly became one of the precursors of progressive rock (along with the Moody Blues and the Nice), mixed in some classical influences, and sold millions of singles but also albums.” Anyone who’s heard “Whiter Shade,” which is likely a lot of people, would recognize the band’s sound immediately on “Repent Walpurgis,” the closing track on the band’s 1967 self-titled first album. The album also featured the track “Conquistador,” which became a hit single, albeit several years later).
JB, who contributed this tune, adds: “PH always managed to retain a rock sensibility, which kept them from crossing the line from melodrama into bombast, or even self-parody … one of the most under-rated bands of the 60s, in my opinion. It’s at least as progressive (at least along certain dimensions) as Pet Sounds or Sgt. Pepper. But even though nearly every self-respecting hippie that I was exposed to during that period seemed to have a copy of this album in their collection, PH never really broke through to the same level of success as Yes, ELP, or other bands mining the same musical vein. My guess is that PH was about 3-4 years too early to really hit the sweet spot of Art/Prog Rock, although arguably they were one of the principal progenitors of that movement.”
Built primarily around C minor, a big transition at 2:15 leads us through a peaceful patch — a melody-less accompaniment for the Bach/Gounod version of “Ave Maria” in C major. At 2:59, we return to C minor.
