Fusing dusty Americana twang and sweet folk sensibilities with an affinity for gnarly art-pop and gritty Memphis blues guitar riffage, the music of Echo Park California’s In the Valley Below is an exercise in contrast. They can be tender and sentimental one minute, a roiling storm of fuzz-injected, sexually charged snarl the next. Fun fact: The band brews its own beer, which it plans to sell at some point — presumably if the music thing doesn’t work out. We wouldn’t worry too much about that last part. ITVB play the Higher Ground Showcase Lounge in South Burlington this Thursday, July 23.
