The highly anticipated, mostly mysterious anime Angel Beats! announced the identities of its musical performers on the Japanese home page. To absolutely no one's surprise, Lia will be performing the opening theme for the 2010 series, after previously providing music for Key's Air and Tomoyo After games. Interestingly, the ending song will be performed by Tada Aoi, who had a brief seiyuu career before reinventing herself as a singer/songwriter - you may remember her as Ed from Cowboy Bebop.
There are still precious few details released about Angel Beats! so far. Aside from the identities of the singers and a few details about the staff, very little is known about the anime, including an air date, a cast, or even a solid story summary. All that's known is that the story takes place in the afterlife, and that the very Haruhi-like main character intends to defy the will of heaven.
