blonde pop singing/acting duo made up of sisters, Alyson Michalka and Amanda Joy Michalka; write their own music together and perform live, usually playing guitars.

Aly's 2 years older, and became known first for her start earlier as an actress in Phil of the Future. She was joined by AJ in the DCOM Cowbelles. AJ usually sings the lower harmony and AJ sings the melody.

Um, you can be over the age of 15 and still love their music. "Don't let nobody tell you your life is over. Be every color that you are!" Lolz, loves it.
You tell Aly and AJ apart because Aly's the prettier one with curly hair, and AJ's shorter with straight hair.
