The 2012 title, which received mixed reviews, came after the band endured a tumultuous period that saw frontman Steven Tyler fall off the wagon, fall out with his colleagues and come close to being fired.

Whitford said last month that Aerosmith "kind of felt abandoned" while Tyler concentrated on his country rock solo album, which had forced them to change touring plans.

Asked about the chances of recording a 16th record, Whitford tells Eddie Trunk: "I really don't know. Joe Perry and I are in the trenches digging away. We're certainly capable of sitting down with the rest of the guys and writing music. If that happens, great. But I'm not going to hold my breath. I really don't know."

He says he's "not really" happy with the idea of Music being their last release, adding that he'd wanted to approach the project differently but he "couldn't get anybody to go along" with him.
