A couple months back, I introduced you to Space Balloons, the kids music side project of Boston musicians Michael J. Epstein and Sophia Cacciola. If you liked the original set of tunes, I think you'll find this new single (and b-side) just as appealing. You've got "Hug War," and then you've got my favorite song title in quite some time, "Hovercraft Full of Eels." Seriously, aren't you just required to download that? Anyway, it's free to download (or stream) via the lovely widget below.
