I keep meaning to listen to the 3x4 album, but haven't gotten around to it. BTW, the new Dream Syndicate album is excellent!
About Nuggets, I got the double album when it came out and then the box as well. I wish I had picked up Sons of Nuggets, but it was OOP and expensive by the time I decided to get it. I do have the SF and LA Nuggets - nice packaging and interesting collections, but they don't hold up as well as the original.
Oh, and one more ... I have the Cowabunga surf box, too! How could I forget??
