In the have not heard, but looking forward to category:
Chris Isaak- Beyond the Sun two disc collection of cover songs from the Sun Studio's heyday in the 50's. Isaak will do well with songs by Roy Orbison, Elvis,Johnny Cash, and others.
The Bridge House School 25th anniversary- The Bridge House School was founded by Neil Young's wife and has an annual fund raising concert. This is a 2 disc collection of acoustic performances from the past 25 years including Eddie Vedder, Springsteen, the Who, CSNY, REM, and others. This one has a great deal of potential and the money goes to a good cause.
