Ann and Nancy Wilson are back in the studio working on their 1,245th project together...this year.

The "Sisters Wilson" still have the guts to try new things, as the Rock 'n' Roll Hall of Fame inductees keep on keeping on.

That being said, it still gives us chills when we see them live and they play "Mistral Wind" from Dog & Butterfly.

Look for Heart on the road for the rest of 2013 -- no Buffalo dates...yet.
