Saturday at 7:30 pm is the second annual iteration of the Summer Jazz Collective, an auditioned all-star high school big band of the best jazz musicians in Oklahoma and surrounding states, who have a camp at OU running at the same time as Jazz in June. This camp allows the students to play with Jazz in June's biggest headliners; last year, they performed with two-time Grammy Winner Chad LB, Taylor Swift's saxophonist, and three-time Grammy Nominee Steve Wiest, Maynard Ferguson's band leader and UNT's One O'Clock director for many years. This year, Adam Neely and Sungazer will join them, as will the horn players from Something Else!
