I found some more great omnichord sounds from a band I didn't know yet.
The Burning Hell is the alter-ego of ukulele player and all-purpose nerd Mathias Kom. While the band can occasionally bloom into a multi-instrumental monster with members all across Canada and Europe, The Burning Hell is now happily based in St. John's, Newfoundland. The essence of The Burning Hell is music to dance to while laughing about death and smiling out of the side of your mouth.
They're touring Europe right now, check them out!
