I think the jury is still out on who actually owned Sidra but apparently it got it's name from John Powers speculating in oil shares in the Gulf of Sidra.

Powers real name was John L.J. Pavlik and he cut some discs for Fortune, Fox, Sun and Tee Pee as a rock-a-billy artist.

He may well have owned Sound Incorporated Studios on Van Dyke and on North New Haven.

Labels appear to be Sidra, Sound, Oceanside, Teen Town, W.I.G., Walker, Maverick, Poo-Pan. Sidrian Music is shown on many releases.

The DREW label was also shown as a subsidiary, and may have been the name of an offspring of the owner.

Ron Murphy recalls that In 1967, entry to the premises was via a door at the centre of the storefront. This gave access to the reception area and two offices. In the centre of the building was the studio, where each instrument was separated by baffles along the left hand wall.

The control room was at the rear of the building.
