Crowbar is one of those bands that the more I hear, the more I like. And Sludge: History of Crowbar has a lot to love. These fifteen tracks spanning a eight year, six album career, is a testament to the dedication to music that Crowbar has. One of the founding fathers of sludge and the New Orleans scene, Crowbar have an instantly recognizable sound that can be heard to progress through out this record. That is the main benefit of a best of album, it offers a retrospective for new and old fans alike. Although this kind of album is often cited as only somewhat noteworthy (according to The Kids In The Hall a best of is for old women and children), a band like Crowbar has more than most to gain from a release like this, generating a larger fan base. Since there is nothing new off of this disk, everything is pretty much what you would expect to find: dissonant, meaty slow riffs that are powered by anguished vocals. Nothing new for the long time fans, but worth a listen for anyone not familiar witty Crowbar.
