Go Away With … Marti Frederiksen

Marti Frederiksen has written songs with an array of artists, including Carrie Underwood, Gavin Rossdale and Buckcherry. But it’s his long-time collaborations with Steven Tyler that stand out. On Aerosmith’s latest album, “Music From Another Dimension,” Frederiksen wrote “Can’t Stop Loving You” with Tyler, who sings duet on the song with Underwood. “It’s really amazing to think about some of these amazing artists I’ve worked with,” says Frederiksen, 50. “Each of them has such a distinct style and I got to be a part of that.”

Taking a breather from tanning, he phoned to let us know why Chicago stores love him, his mixed feelings about downloading music and why his kids made him change his bathing suit.
