I don't think it's necessarily dying, it's just become derivative. I like The Fray and Snow Patrol and all, but I have to admit they do get far too analogous after awhile. At least Keane went somewhere different on their new record. That's what makes this disc so special. It takes a few chances and goes a few places most people wouldn't.
Good review. Checked out his songs on Myspace and immediately got the cd on iTunes.
Some other good piano-rock bands worth checking out are: The midway state, Until June, Dikta, The Reign Of Kindo, and Lost Ocean
