Cate Le Bon’s new Rock Pool EP features wonky songs left off last year’s excellent Crab Day album. The Welsh singer-songwriter creates psychedelic pop songs that can be read either as very silly or very serious. (It’s a little like listening to Broadcast or Stereolab.) Le Bon’s also a great video artist, whether she’s drinking a glass of wine with a horse (“Shoeing The Bones”), wandering amongst modern dancers (“Love Is Not Love”) or strolling through a lunar-looking field with a very tall hat on (“Rock Pool”). The free show also features Tim Presley and Rachel Blumberg.
