45 Grave was an American rock music group active from 1979 to 1990.
Formed in Los Angeles during the punk rock movement, 45 Grave created their own brand of "death rock". The original lineup consisted of Dinah Cancer on vocals, Paul Cutler on guitar, Rob Ritter (also known as Rob Graves) on bass, and Don Bolles (of The Germs) on drums. The band evolved out of a proto-industrial music band called Vox Pop, who recorded two singles and played around the Los Angeles area, including an opening slot for the final performance of Throbbing Gristle in Culver City. Vox Pop contained all of the members of 45 Grave as well as others such as Jeff Dahl. Vox Pop continued to coexist with 45 Grave until early 1981.
In 1980 45 Grave recorded their first song, "Riboflavin Flavored Non-Carbonated Poly-Unsaturated Blood", an obscure cover from the 1960s, on a small TEAC 8-track recorder, which was released on the LAMFS compilation. Their name, despite rumors to the contrary, was lifted from a button. The band soon took the deathrock, punk and goth scenes by storm.
