It has all the makings of an April Fools joke, but this one is really happening, folks. The first release from the upcoming album, "Piss Off," is pretty comedic and lighthearted, so it'll be interesting to see what the rest of it sounds like. It's also not too common for two entire bands to get together for a collaboration, but it seems to have worked out pretty well for them thus far.

What are some of your favorite musical collaborations?
