Twenty years ago this month, Outkast released 'ATLiens.' It's an album and group that mean a lot to Mary Nahorniak, as she explains in this week's 'Tuesdays With Mary' segment on Dad Rock.

'Tuesdays With Mary' is a weekly feature of Dad Rock, a music podcast from USA TODAY hosted by Patrick Foster and Jim Lenahan.
