For all of the old school, retro-rock bluster, it is not all that Barn Burner is. There are some punkish turns, such as "Long Arm of the Law," while others have a somewhat Mastodon-like quality to them, like "Medium Rare." Barn Burner does fall squarely in that rock category, but their influences come from all corners and blend into an easygoing, yet still intense, hard rock that will hold your attention once you get hooked.
I can only imagine what this is like in a live setting. I can see a floor filled with guys rocking their heads, beers held high in acknowledgment of what is happening on the stage. I can see the band up on the stage, playing through a cloud of smoke and multi-colored spotlights, asking for the monitors to be turned up. They are ripping through the rocking tunes with reckless abandon, occasionally flipping out a little while emphatically swinging their guitars in time to the riff. I don't know about you, but that sounds like a good time to me. Besides, how can you go wrong with a band that has a song called "Beer Today, Bong Tomorrow"?
Bottom line. If you like rock and roll with a good groove, check out Barn Burner. Barn Burner is a band that is about a rocking good time; their music is proof positive of that. What else do you really need?
