Following up on their sold-out two-night stand at the Mann Center last summer, improvisational jam band Phish are coming back for round two. Perhaps aiming to out-vibe themselves, the foursome will make their Philly comeback, again at the Mann, on Tuesday, Aug. 11 and Wednesday, August 12.

Tickets go on sale at 10 a.m. on Thursday, April 2, though you can now begin requesting them now through Sunday, March 29.

Phish's Trey Anastasio is also set to perform at The Grateful Dead's final performances in early July at Chicago's Soldier Field.

Also on the docket for the band is their impending Record Store Day release, their first-ever full-length live vinyl box set, "New Year's Eve 1995: Live At Madison Square Garden," out April 18.
