Program Services

DescriptionGrantsExpenses
In the first full year of our incorporation and semi-year of non-profit status (501c3), Improvise Arts hosted numerous free events. The first Tuesday of each month in January, February, March, April, May, September, October, and November, was our "All Ages Jazz Jam Session" which served over 100 different highschool and middleschool aged youth with 10 different mentors from the community that work/will work with Improvise Arts. Average audience attendance was 65 people, and an estimated 1,200 people ended up coming to the Jam sessions during 2024. Additionally, in 2024, Improvise Arts sent its Executive Director - Alex Massa - to 5 different high schools in the region to put on masterclasses, sectionals, and individual lessons in Jazz, Black American Music, and Improvisation/Spontanenous Composition. During 2024, ED Alex Massa worked with over 500 students in the Black Hills area. On December 3rd, 2024, IA hosted its first fundraiser - a Jam Session at a local establishment, that raised nearly $8,000 and had approximately 200 people in attendance to learn about the organizations mission.$0$2,500
