She is the adopted daughter of vocalist Marvin Lee Aday, better known as Meat Loaf, and was a member of his touring band Neverland Express for nine years starting in the mid-1990s.

Aday also co-organized the hard rock group Motor Sister with her husband Scott Ian, singing backing vocals.

Aday was born to Leslie G. Edmonds and Clark Pierson, who was a drummer in singer Janis Joplin's group, Full Tilt Boogie Band.

Aday went to Emerson College in Boston, Massachusetts, majoring in creative writing, but shortly thereafter began a music career.

She was also with a Los Angeles-based band named Stella, fronted by Nancy Hower (Star Trek: Voyager), which broke up before releasing an album.

In May 2009, she appeared on the FOX game show "Don't Forget the Lyrics" along with her father Meat Loaf and his duet partner Patti Russo: they won $500,000 for charity.
