While Pepper Keenan has been keeping busy with Down, the remaining members of Corrosion Of Conformity’s Animosity lineup have been touring and recording new music. In interviews, Keenan revealed that they had been talking about him rejoining the group for at least a few songs onstage in Europe. Well it looks like they finally called him back.

During C.O.C.’s set at Kristonfest in Bilbao, Spain this past Saturday (June 18), the band was rejoined by Keenan on vocals and guitar. This marks the first time Keenan performed with C.O.C. since they went on hiatus in 2006. It is unclear at the moment, though, whether Keenan will join them again onstage in the near future, or whether he will appear on the newly recorded material the trio is working on.
