Boston says their next album is "85% complete", and that the disc will include vocal tracks recorded by their dead singer Brad Delp.  There aren't any specifics, except that you'll hear him on, quote, "many songs."

Stryper singer Michael Sweet, who joined Boston for their 2008 tour, did not participate in the recording of the album... but Tommy DeCarlo did.  He's the guy the band discovered on MySpace after Delp's suicide in 2007.

This will be their first studio album since "Corporate America" came out in 2002.  There's no title or release date yet.
