Mariah Carey kicked off "Good Morning America's" Summer Concert Series with three songs from her latest album, "E=MC2."
You don't have to be Albert Einstein to like the album's hit formula. "E=MC2" is already No. 1 on the Billboard Hot 200. A veteran of the music scene, her 11th studio CD was released April 15.
Also No. 1 is the DVD of her last concert tour, "The Adventures of Mimi," re-released and now at the top of the Billboard Top Music Video chart. (Ida Mae Astute/ABC)
