My brother Mike (who wrote a post on this blog about Metallica a couple of years ago) is a pretty big fan of Bad Religion, so he's much more qualified to talk about them than I am. He says that the album has "one heck of a setlist," and that the first and last songs, which are from their debut album, "sound light years better here!" Also, if you visit the band's page on the Epitaph site, "you can click on the album covers on the bottom of the screen and download 1 or 2 songs from almost every single one of their releases. and that includes a few of their best songs, i.e. 'sorrow' from The Process of Belief. altogether you can download enough for a really nice little unofficial greatest hits record."
Okay, so this wasn't as short as I'd thought it would be, but that's mainly thanks to Mike. I hope you enjoy the album, and also the free MP3s from the record label's site if you decide to check then out. Happy listening!
