As reported by Dolores O'Riordan Spain and Cranberries World, during an interview in Peru promoting The Cranberries final tour date of the year, Noel and Fergal revealed details of the band's upcoming albums:
They announced a tentative release time for the the previously announced album of reworked songs with the Irish Chamber Orchestra, May 2017. (This, again, is tentative, it's best to lower your expectations and add about 3-6 months to these release dates). The big news is that along with reworked versions of some of the band's best songs, the album will also include 3 brand new songs!
The other big news is that they said they are writing songs for an all new album with all original songs! They hope to record it after a promotional tour for the acoustic album!
2017 looks bright for The Cranberries!
