Heart are working on a new album that they hope to release in the summer.
Wilson adds that the follow-up to 2012’s Fanatic will have “more contours” than its predecessor.
She says: “Fanatic was our heaviest album we ever did in terms of banging and crashing, big guitars and all that kind of stuff. This one will have more contours.
Wilson describes one of the tracks, written by sister Nancy, as “very sweet and just tugs at your heart.”
Heart have a number of North American tour dates coming up, starting in California this month. They play four UK shows in June and July.
