There are a handful of labels that I always trust because the music that they produce is always top-notch. When it comes to indie-rock and pop, Oakland’s Slumberland records might just be my current favorite. One of their most recent releases is from The Mantles, a garage pop group out of the Bay Area. There sound is an interesting one, because it’s not simply a revivalist take, but has a few elements of the 1960s, 1980s and 1990s. “Bad Design” is a good representative, of this sound, imminently poppy, with a little jangly guitar, subtle washes of organ and percussion mixed with a gritty style admist the sunshiney melodies. All in all, sure to get more than a few spins here in the Summer.
