Well its about time! I love these ladies and can't wait to see what they come up with. There new album will be released in summer of 2010, there last one was "Jupiter's Darling" way back in 2004.
Here is part of an interview with Nancy:
LOS ANGELES (Reuters) – Rock 'n' roll sisters Ann and Nancy Wilson of Heart have been making music together for more than 30 years, but they have rarely shared the vocal spotlight.
Ann did most of the singing, while guitarist Nancy occasionally contributed backing vocals. The formula served them well, producing such classic-rock chestnuts as "Barracuda" and "Crazy on You."
But things will be a little different for the group's next album, on which they are currently working. Nancy will take a greater share of the vocal duties as the sisters experiment more with harmonies.
"It's just a way of reinventing, and having more fun, and taking some of the pressure off of Ann as a singer," her younger sister said in a recent interview with Reuters.
"As you probably can imagine, her voice is really a gift from above. It's an instrument like few others. To couch a vocal style together more would be something fresh and new and more fun. Harmony singing is my favorite thing to do in music!"
Wilson described her vocal style as "more limited," although she has sung lead on a handful of tunes including the 1985 chart-topping power ballad "These Dreams." The sisters also notably traded off each other on their cover of Led Zeppelin's "Battle of Evermore."
"I love singing, and whenever I can sing some more vocal leads I always covet the chance. But it's always got to be the perfect fit for a voice like mine," she said.
