Egokiller is an Indie Alt Psych trio from Leeds in the UK, but they'll experiment with any sound or genre that feels right. They feel they're carrying on in the grand tradition of bands like the Grateful Dead and Phish and polish is not what they're after. Their recordings are done in one take with band members encouraged to follow their muse and improvise as they record or play. It can end up sounding chaotic or it can end up sounding like heaven. Ultimately, which is which is up to you.
The free track, here, is "Santa Claus Is Coming To Town". But that's really an enticement for you to check out the full EP, "Monster Chunks & Mistle Toes" (which is not free). My favorite from the full EP is "Three Wiser Men", which not only boasts the clever title it does, but legitimately does sound like a throwback to the wilder Psych bands of the Haight Ashbury era. Check it out on Bandcamp.
