MADISON, Wis. — Dennis Graham Associates, in association with the not for profit MAMA (Madison Area Music Association), is kicking off the 15 year producing a statewide youth garageband competition, showcasing only Wisconsin seventh- through 12th-grade bands of all musical genres.

“Rockonsin,” sponsored by the Nicholas Family Foundation, will invite 12 statewide Wisconsin high school/middle school garagebands to perform and compete at Summerfest. The performances and competition will be conducted on the Johnson Controls World Sound Stage over two days — dates and times to be announced. The winner and runner-up will each receive studio recording time at Madison’s Blast House Studios.

The band application period is open and will close April 30; bands can sign up at www.rockonsin.org.

Rockonsin features:

■ No registration fee; never any associated costs to participate.

■ Musicians applying do not have to be enrolled in a traditional school music program, and the band must be comprised of two or more musicians, one member of the band must be a vocalist.

■ Each band member of the 12 statewide bands selected to perform at Summerfest must submit a school document verifying the Wisconsin school they are attending; more information can be found at www.rockonsin.org.

■ Each band will be asked to submit one video (bands should not incur the expense of professionally videotaping their song, using a smart phone or a hand held video camera will do the trick) of the band performing either one cover or original song and submitting a link to that video, in addition to filling out their band application at www.rockonsin.org. Bands should video close enough so that one can see the band members actually playing or singing; and include the songwriting credit and lyrics.

■ The one song video application will be reviewed by a panel of music industry professionals and bands will be notified by May 15 if they have been selected to perform at Summerfest.

■ The State Finals set times are 15 minutes for each band, with the winner and runner up receiving a second 45-minute session. And each 12 bands will receive two Shure microphones per band. The winning band will also receive from Shure, a free wireless vocal microphone system.
