 SHS Jazz Band Members
Named to ATSSB Jazz Band

On Saturday, September 17th, the SHS Jazz Band competed at the ATSSB Region 3 HS Jazz Band Auditions at Crandall High School. The competition was tougher than ever this year, with many sections doubling their number of students auditioning. The SHS Jazz students did a wonderful job representing SISD, and the following students made the group:

--Seth Fredrickson, Alto Saxophone 1st Chair Region and Area Jazz Qualifier
--Kelsey Pormasdoro, Alto Saxophone, 1st Alternate Region Jazz
--Jacob Bradford, Trombone, 2nd Chair Region Jazz and Area Jazz Qualifier
--Kayla Pormasdoro, Piano, 1st Alternate Region Jazz
--Jenna Melofsky, 1st Chair Region Jazz and Area Jazz Qualifier

 These area qualifiers recorded their professional tapings to be sent to the area rounds next month. If the students make the cut, they would then advance to the state Level of Jazz Auditions. 

Way to go to all of the Sunnyvale Jazz Students who worked hard on the music and came out to the auditions.
