UNSC Jazz Band
From Halopedia, the Halo wiki
The UNSC Jazz Band[1] is a instrument ensemble/group, likely consisting of around twenty members forming a rhythm section and a horn section. All members are presumably part of the UNSC Defense Force.
In 2550 the ensemble closed out a three-hour United Nations Space Command promotion ceremony in downtown Quezon on Reach. It was at this ceremony that Miranda Keyes was promoted from Lieutenant to Lieutenant Commander, awarded the Silver Star, and given command of her own Stalwart-class light frigate, the UNSC In Amber Clad.
