Aly Michalka grew up in Seattle, where she learned to play the piano (at age 5) and guitar (at age 13). She also began acting at five years old, appearing mostly in church productions. She made her debut in the Disney Channel series Phil of the Future, which lead to roles in other Disney productions, notably the TV movie Cow Belles, opposite her sister Amanda.
Aly is perhaps best remembered as one half of the group Aly and AJ, a pop-rock act with her sister. The two released their first album, Into The Rush, in 2005, and saw moderate success. Their third album, Insomniatic, was released in 2007 and featured the Top 20 hit "Potential Breakup Song". The group has since renamed themselves as 78violet.
Aly also pursued a solo music career, performing songs for the Vanessa Hudgens-fronted flick Bandslam. She also performed one song for the CW series Hellcats, which she joined in 2010 and currently plays the lead on.
