We love the mingling of past and present that so often happens in roots music. We revere the sounds from the past while cheering on the folks who find an entirely new way to bring those sounds into the modern world, whether it’s by re-recording old songs, as with the Red Hot project paying tribute to Sun Records, or writing new ones with an eye toward tradition, as Molly Tuttle does on her debut EP. Whether you’re old-school or new-school, a dropout or a Ph.D., there’s plenty to tickle your brain amid this month’s new releases.
