Aly and AJ Michalka make beautiful music as 78violet, and the singing-acting duo may be the busiest sisters in the biz.
The musical siblings are multiple threats as singer-songwriters, actors and even video game accessory designers (with a signature line of guitar controllers for Wii, Guitar Hero and Rock Band), not to mention's Aly's illustrations in their four-book series Aly & AJ's Rock 'n Roll Mysteries. In addition to working on a new album as 78violet, AJ is currently starring on the big screen in 'Secretariat' and will next have a role in J.J. Abrams' upcoming movie 'Super 8.' Aly can be seen on the big screen in 'Easy A' opposite Emma Stone and on TV in The CW cheerleader series "Hellcats" opposite Ashley Tisdale.
"It takes a certain amount of focus and fearlessness to be involved in that sport," says Aly. Although she has no formal training as a cheerleader, their mom was a cheerleader for the Rams and Raiders and UCLA, "so I definitely have some legit blood in me."
The two appear to get along famously and insist that there's no sibling rivalry between them: "We go out for the same parts every once in awhile, and that we kind of laugh about because we're completely different people," says Aly. "Even if [one of us did land it], I think we would be super supportive of each other, because if I want anybody else to book a role that's not me, I want it to be AJ."
Aly and AJ (21 and 19 years old respectively) are moving on from their previous personas as "Aly & AJ," having already become platinum-selling artists with two hit albums and back-to-back sold-out tours in 2006 and 2007. They were nominated for an American Music Award, and their "Potential Breakup Song" has been RIAA certified with sales of more than a million downloads. So why the change?
"We're women now and we're growing up," says AJ. "It was time for a change."
"Our sound is changing, and the changes that are happening are natural and it's been a slow progression," says Aly, who explains the origins of their new band name: "Purple and violet have been a huge part of out lives -- it's a really powerful color. … 78 stands for platinum in the periodic table of elements. … The definition of platinum means that no substance can corrode it, and I was like, 'Dude, that's our relationship. We cannot be corroded. Our relationship as sisters is unstoppable."
