I'm a Keyboard Player and a 33 year Musician, and an Elvis fan! A devoted follower of Jerry Lew Lewis and ALL the Sun Family. Sam Philips was smart enough to put an open mic in the room when this Jam Session happened. Elvis sings like he's in church on Sunday morning, wit so much feeling. Jerry Lee can't be lost no matter how many times Elvis switches songs. He grew up the same way.Carl Perkins thumbstyles that Guitar like the Lead Man he was! They stop and start, like it was all for fun (which it was). No formed up songs, no perfect clean things, Just raw gospel and country with a Rockabilly flair. I swear I didn't know these tapes existed, and I'm a music history idiot. Thank you for selling them amazon!! Any Elvis fan needs this one!! BUY IT!!
