Showcasing a purple, leather-clad ass on the cover of your new album is a good way to attract some to the artwork, but as far as opening up the package and listening to what’s inside—that’s another story. The Donnas are the Runaways, if you will, of modern rock and roll: Girl power is their message and they’ve got the look and the sound to stay on the scene. Like many other groups, these four got together when they were just kids, in 1993, and gave birth to their band out of someone’s garage in Northern California. Seven studio albums later, they’re still going strong and, thanks to the bonds of friendship and a deep trust in one another, they’ve managed to accomplish a feat most other groups cannot: simply staying together. Their latest album, Bitchin’, the first record off their new label Purple Feather Records, represents a departure from the world of the corporate record industry. They wanted to do it their way and they made it happen. Citing influences such as Aerosmith, Motley Crue and Def Leppard, the Donnas may have felt “sceneless” for a while, but now relate the most to the metal crowd. They even have their very own cult following (known as the Donnaholics) and have proven they have what it takes to be rock superstars. Support from Donita Sparks & the Stellar Moments and the Switches.
