afaik....
- Edgar Winter's White Trash With Jerry LaCroix,
- They Only Come Out At Night,
- Shock Treatment,
- Jasmine Nightdreams,
- The Edgar Winter Group With Rick Derringer.
Then I would also lump in his brother Johnny Winter's Quads..
- Still Alive And Well,
- Saints And Sinners,
- John Dawson Winter III
and why not go for broke and do Edgar's mate Rick Derringer's Quads for good measure!
(to a certain extent, Derringer and Edgar W.'s personnel/band line up's were kinda interchangeable at one point
and Johnny, Edgar and Rick all played on one another's records numerous times over the years..)
- All American Boy,
- Spring Fever.
That's a cool TEN Quad releases for Audio Fidelity to do on Surround SACD right there.. and let me tell you there is not a clunker of a mix in the bunch! In fact they are all great examples of Quad imho
Also, Johnny Winter's Self-titled debut is an unreleased confirmed Quad as is Edgar's "White Trash". There was a magazine article from back in the day that said "Roadwork" was coming in Quad, but it never appeared. Some have suggested the LP is a hidden SQ but no Q8 or unreleased reel has ever surfaced.
