On heavy rotation this week in my brain: Atlas, by Battles. Formed from the ashes of several other like-minded bands, Battles is an experimental math-rock group who has released albums sporadically over the last 20 years. Atlas is a single from their first album in 2007, and it defies description. I originally fell down this rabbit hole when YouTube suggested a video of early math-hardcore band Helmet playing live in 1994; their second album Meantime was on heavy rotation in college, and their original drummer went on to co-found this band. This song and the video are amazing.
