Earlier this summer, I picked up this compilation set of the McAllen, Texas music scene of the late 1960's. It features a variety of different acts, but the main act that anchors this set is Christopher and the Souls. This group became well known in the Valley after a famous eBay auction and an article by The Monitor. That article talks a bit about their song, "Broken Hearted Lady", which I uploaded on my YouTube account here (which I acquired thanks to this neat compilation):
Here is an interview they did right before they were set to perform at SXSW 2010.
