Post-grunge outfit Creed have added a slew of shows to their upcoming spring tour. The outing, which begins in April, will see the group perform the entirety of either "Human Clay" or "My Own Prison", their two most popular albums, plus a smattering of other hits.

“I’m excited that we will be able to turn these initial select few shows into a full fledged tour. It means a lot to us that our fans wanted more shows and we look forward to performing these albums for them,” lead singer Scott Stapp said.

While the group is at work on a followup to 2009's reunion record "Full Circle", they have not set a release date for the album. Alter Bridge, the group formed in the wake of Creed's initial breakup, are on a scheduled hiatus in order to allow singer Myles Kennedy to finish recording an album with ex-Guns n Roses guitarist Slash.

Though never gaining much in the way of critical respect, Creed have been recognized as one of the preeminent acts of the late 90's post-grunge boom. They have sold an estimated 35 million albums to date. Just prior to their initial hiatus, the group were the subject of rare praise from Slate Magazine.

"Most people hate Creed’s combination of overwrought power-balladry and Christian-infused testosterone," wrote Jonah Weiner. Weiner went on to describe the band as "seriously underrated." Other magazines haven't been so kind, going so far as to call Creed "an unremarkable, plodding muscle-bound reworking of Pearl Jam, with all of that older band's warmth and psychological intensity replaced by chest-beating bravado and blandly messianic lyrics."
