Acoustic favorites and jazz will fill Rock City Café, 316 Main St., Columbus Day weekend. Live music will run from 7 to 9 p.m. both Friday and Saturday, Oct. 7 and 8.

Happy Folk, performing Friday, comprises a rotating bandwagon of friends and family wrapped around the music and philosophy of Nik Hasenfus and Aria Zarnoski. The two songwriters attempt to dissolve the boundaries created by the performing arts, combining their ambitions of authentic relationships as well as similarly natural genres of music.

The current core duo is Portland-based these days, exploring a new musical identity with each new friend and each new day. Happy Folk plays old favorites and new original material; and has a demo EP in the works.

On Saturday, Rock City will welcome back the local Mike Whitehead Group, dedicated to the exploration of creative improvised music. The band features Mike Whitehead on trumpet/flugelhorn and processing, Tom Luther on keyboards, Jason Dean on percussion and Spike Hyssong on acoustic bass. Firmly based in the jazz tradition of improvisation, MWG includes the free use of funk, rock, folk, ambient and electronic music in its musical explorations. The concert will feature original compositions and compositions by artists they love.

Food is available until closing. For more information on these and other events happening at the coffeebar/cafe, call 594-4123 or find it on Facebook.
