Mates of State/Bethesda

: Beyond the longevity of Mates of State’s rock ’n’ roll marriage, the duo continues to release new and challenging works. They constantly switch things up dramatically from one album to the next. The relatively straightforward indie rock on their debut My Solo Project was offset by the synth-laden, increasingly complex tracks on 2011’s Mountaintops. Regardless of the album, the music burns with energy. Driven by bouncy hooks and beautiful singing, tracks like “Maracas” and “Unless I’m Led” passionately move the listener to elevated head spaces. Locals Bethesda and Leah Lou & the 2 Left Shoes open the show. Both groups offer their outstandingly unique takes on indie pop. (Stoops)
