One of the secret weapons of the Velvet Underground was Lou Reed's Ostrich Guitar Tuning, where all the strings were tuned to D. It got its name from the 1964 novelty single "The Ostrich" by The Primitives, a pre-Velvet Underground band fronted by Lou Reed. Originally only a studio project, the song about a fake novelty dance generated enough interest to put together a band for a few live gigs. And amazingly enough, that touring version of The Primitives featured John Cale, Tony Conrad, and Walter DeMaria. While I am not aware of any surviving live recordings of these guys, here are both sides of the studio recording in MP3 format: The Ostrich | Sneaky Pete
Only one year later Lou Reed and John Cale would form the Velvet Underground and never record a novelty dance number again.
