Trout returned to his hard-core blues roots on his most recent album, “Blues for the Modern Daze,” which was released this past spring, it says on the C2G website, www.c2gmusichall.com. It is Trout's first pure blues album in 23 years as a bandleader.

ROAD TRIP: The annual Auburn Cord Duesenberg Festival will fill downtown Auburn with some of the most eye-catching cars ever made. Admission to most activities is free.
The festival features a week of activities, but it really ramps up Friday through Sunday. Here are some highlights:
•Friday: The Downtown Cruise-In begins at noon around the DeKalb County Courthouse square.

•Saturday: The festival highlight always is the Parade of Classics, which takes place at 1 p.m. Auburns, Cords and Duesenbergs will roll through town to the courthouse square, where they will remain on display until 4 p.m. The theme for this year's festival is “Year of the Unrestored Car,” so you'll see as many as two dozen cars in various stages of restoration.
•Sunday: Enjoy the arts-and-crafts show 9 a.m.-4 p.m. in downtown Auburn.
At least two celebrities also will spend the weekend mingling with fans in Auburn:
•Three-time Indianapolis 500 winner Bobby Unser will be grand marshal for the parade at 1 p.m. Saturday. He'll also be at Auctions America by RM auction park throughout the weekend.
