If the press release for RMBLR's "Main Muscle" shows the "lighter side" of the band, I'm almost afraid of what they normally sound like. Sure, "Main Muscle" isn't the softest song out there, but it's still a punk rock song. It reminds me of Rancid, and only the crustiest of punks are going to say Rancid made soft music. RMBLR's new song may be on the pop side of punk, but this might be the heaviest pop punk song you've ever heard. It has roots in bands like the New York Dolls, but with more of a hardcore sneer.
You can watch the video for "Main Muscle" below. The song will be out as a single on May 14. MF/EP is due out in June on Spaghetty Town Records and is available for pre-order here. For more on RMBLR, check out the band's Facebook.
