This is catchy pop-punk highly reminiscent of Green Day. In fact, MXPX could be called "Green Day clones" for the most part, but they do a better Green Day than Green Day themselves. While I think that Green Day successively has become worse, MXPX have produced an album that combines the best of Green Day's first three albums. The songs are extremely catchy, fun, and high energy à la the Clash and the Sex Pistols (in fact, the band apparently shared the stage with the Sex Pistols on their recent tour). If you're into energetic pop-punk, this is definitely the band to check out!
