I'm listening to The Wall by Pink Floyd. It's such an amazing musical masterpiece. I don't know why everyone gives Darkside of the Moon sooo much praise and love. The Wall is more dynamic and contains so many themes. I'm going to a Pink Floyd tribute band (Wish You Were Here, Cleveland, OH) performance recreation of The Wall stadium tour from 1980-1981 in July. I listened to a demo of the band on their website and they're pretty damn close to capturing the original sound of Floyd. Check them out at floydtribute.com! Sorry for the shameless plug but I love Pink Floyd in any form.
The Doors Live in Pittsburgh 1970, it's a great archive release, I can't wait till the next one in their series, Live in NYC comes out, I hear it's supposed to be a four cd set with two or three full live shows.
