Back in the mid-70s, the Wilson sisters of Heart were rocking harder than a lot of men that were around. With “Crazy On You,” “Magic Man,” and more, their 14 albums have sold millions of copies. But their career wasn’t without issue: In an act of mid-70s chauvinism, the band’s label tried to market sisters Ann and Nancy Wilson as lovers. But it wasn’t all bad, since the questioning of the sisters’ relationship caused Ann to angrily write “Barracuda.” So now we have “Barracuda,” and “Barracuda” is great. Heart has experienced a bit of a resurgence in recent years, with their album Red Velvet Car hitting #10 on the album charts two years ago, and they are on the road playing new songs and old classics alike. They’ll be at the Tower Theater this Friday, and we want you to go. To enter to win tickets, email ihopeiwin[at]philebrity[dot]com with “OOOOO BARRACUDA” in the subject header.
