Any band that names a song “Bone Jam” probably wants to melt faces. That’s certainly the aim of Jeff The Brotherhood, a pair of hard-partying brothers from Tennessee whose 2009 debut, Heavy Days, could be fairly said to shred. But the brothers bring more than just furious solos to their tight compositions: There’s a strain of power pop that runs through the songs, with vocal harmonies laced throughout arrangements that otherwise rumble and churn. The dichotomy is what propels the band’s songs forward; that it’s just two members making such a racket is even more impressive. Their latest album, We Are the Champions, was released this June.
