The Modulation Corporation made one 45 on Atom 1001 in November, 1967: the tough garage song “What to Do” b/w the bluesy “Worms”, both written by Francis W. Wilson II, and cut at Texas Sound Studios in San Antonio.

I don’t know the names of other members in the group. Francis Wilson seems to have been known as Billy Wilson. Covering the wedding of Jane Ellent Grant and William Eilers Jr. in Luling, TX, the Shiner Gazette on December 7, 1967 mentioned “An orchestra, Billy Wilson and the Modulation Corporation, provided music during the reception.”

The Modulation Corporation seem to have been together only during the fall of 1967. I’ve read the group was from San Marcos, about halfway between Austin and San Antonio, but most of the notices I’ve found are from two Austin venues, the Lake Austin Inn and the Pleasure Dome.

They had regular gigs at the Lake Austin Inn in September and October, 1967

On December 29-30, 1967 the Modulation Corporation played two nights with the South Canadian Overflow at the Pleasure Dome, and may have been included in the New Year’s Eve show with the Golden Dawn, Lightnin’ Hopkins, and the Afro-Caravan.

Anyone have a photo of the group?

The Pleasure Dome

The Pleasure Dome opened on December 15, 1967 with the Thingies and underground films like Scorpio Rising. It was located at 222 E. 6th Street in what had been the Yank Theater building. Bill Simonson managed the club, with lighting by an unnamed person who had done lighting at the Electric Circus and the Cheetah in New York City. In progress off the lobby was the Sacred Mushroom Bar.

From notices in the American-Statesmen, the Pleasure Dome seems to have lasted only one month.

The first week of January the Pleasure Dome had the Thingies and South Canadian Overflow on Friday, the Strawberry Shoemaker and the Golden Dawn on Saturday, and the Golden Dawn and the Thingies on Sunday.

The following week featured the Thingies, the Starvation Army Band and the Vines. I have found no further notices after that.
