I found some free time this weekend to revisit some freebies from Amazon's Artists to Watch series that I'd given a cursory listen a while back. One song I really enjoyed with a bit of concentration was Hooray for Earth's track 'Keys'. 'Keys' is syth/electronic rock with heavy riffs and soaring vocals. Toss in a guitar solo too for a toe tapping head bobbing bit of fun. 'Keys' is the Aimless Skylarking Song of the Day, stream it below.
