The monthly "Jan Winkelman 5:01 Jazz Series" — a series of free Friday concerts at Goodnite Gracie — returns this weekend for a new year.

The series is sponsored by WEMU (89.1-FM), the jazz and blues public-radio station at Eastern Michigan University. It is named for the late Jan Winkelman, a longtime supporter of WEMU.

The concerts feature a relaxed, after-work vibe. (5:01 is the start time.) Most, though not all, of the shows are on the first Friday of the month.

Concertgoers will have the chance to rate the bands that play, with the top three acts getting an additional showcase to close out the series.

The full lineup:

• Sept. 11: RJ Spangler Trio

• Oct. 2: The Keller/Kocher Quartet

• Nov. 6: The Royal Garden Trio

Listen to Royal Garden Trio "Blue Drag" (MP3).

• Dec. 4: Hal Davis and Hi Def

• Jan. 8: Los Gatos

Listen to a sample of Los Gatos "Con Su Bataola" (MP3).

• Feb. 5: Chris Codish Trio
