Tyler teased in an interview with Rolling Stone that the as-yet-untitled record is Aerosmith's greatest work in decades.
"It's one of the best Aerosmith albums ever [and] I'm one of the worst judges of my own music because I'm very harsh, highly critical," the singer explained.
Tyler went on to suggest that he's particularly proud of Aerosmith's new LP because the band took time to really craft the songs.
"We waited until we had at least four really good songs that were representative and we got 19," he revealed.
Aerosmith are expected to release the album this summer.
The group will kick off the 'Global Warming' tour on June 16 in Minneapolis, MN.
