Query: Unreleased tracks finally released for all to enjoy

Pearl Jam has compiled a lot of hit songs through their tenure. With Lost Dogs, the fans are given a treat beyond belief; B-sides that are not filler tracks. A great double CD set that covers thier long standing in the grunge music scene. If you like them as much as I do I think you will love Lost Dogs. Many of the songs I noticed are really hard edged and remind me of their earlier releases like Ten and Vs. Other songs on here are also psychadelic and drifting. I think a long time from now people will be talking about this band, and also this very dual CD set. I wasn't a big overall Pearl Jam fan but Lost Dogs has me liking them more than ever. I give it five stars for that reason.
