75 Jeff Tweedy Age: 46 Occupation: Musician

Lately, Wilco’s frontman has been spreading the magic—as a producer. His assured touch in sessions with Mavis Staples, Low, and Sarah Lee Guthrie and Johnny Irion earned him a 2013 Grammy nomination for producer of the year (he lost to golden boy Pharrell Williams). Coming this year: a new Wilco record, which Tweedy has said will be “a little more fucked up than the last few.”
