From Alas, a blog:

Sugarshock is Joss Whedon’s free on-line comic. If you haven’t read it yet you should: part 1, part 2, and part 3.

I’m not one to argue with Alas. It’s about a mostly-girl band (also robot. also groupie) and their intergalactic travels. Vikings are bad. Sad songs are good. Enjoy. Don’t expect it to make much sense.
