Orgasm (later reissued as Cave Rock) is the only album by the experimental band Cromagnon, released in 1969 by the ESP-Disk record label.

"[3] Another critic, describing the album, said: Now, when you stick the needle into the groove that is opener, "Caledonia", you'll immediately think you're listening to Einstürzende Neubauten gone black metal, then you'll realize you're WRONG and that there was no reference points such as that available in 1968.

[2] Music author Jason Weiss wrote that the album "eventually developed a minor cult following and was hailed as a pioneer in sound collage experiments".

[5] AllMusic's Alex Henderson writes of the album: "Depending on one's point of view, Cave Rock is either a ridiculously self-indulgent artifact of the '60s counterculture or an underground gem that was way ahead of its time – and it's probably a little bit of both.

Still, there’s no question that Cromagnon achieved something remarkable in its strange concoction of noise, spoken word, folk, electronics and field recordings.
