Great band! I saw Edgar Winter’s White Trash at The Warehouse in New Orleans in 1971. Solid rock and roll. Rick Derringer had these crazy jeans with eyes embroidered on the back pockets. I’m thinking they opened for Ten Years After, but it was a long time ago. ;-)
ah. The Warehouse. Saw many concerts there. I am not sure I saw the concert you mentioned but I saw Ten Years After, Pink Floyd, ELP and others at that venue.
In those early years you could get quite close to the stage. In 1970 I saw Pink Floyd when there were probably less than a hundred people there. I was able to lean on the stage just a few feet from the band.
