TL;DR: No, not really, at least none that play exclusively music that is not classical. (warning, wall of text) Respectfully, what else would they play? An ensemble of this calibre that trains musicians to succeed in the professional world (where they will be playing almost exclusively classical music, or at least "classical" band music) has to play literature that is challenging enough to help the musicians grow, in addition to putting on a good performance. Many concert bands (and orchestras especially) sometimes do "pops concerts" where they play popular music (oftentimes around the holiday season) and community outreach concerts to reach new audiences but these people devote their lives to performing classical music, or classical band music, so much so that it would kind of be a waste of their talent to spend much time on anything else, especially for pop music where the focus of the music is usually not on the melodies or harmonies or timbre or form. Now if you are thinking more along the lines of standard jazz or blues repertoire, concert bands do play in those genres-there are many composers that write jazz or blues or whatever concert band music that is challenging enough to be worth the while of a largely student ensemble like this one (the first example that comes to mind is "Blue Shades" by Frank Ticheli, but there are countless other examples across many genres). A lot of folk melodies are incorporated into classical music and band music (see Grainger's "Lincolnshire Posy", as well as pretty much most Romantic-era orchestra music) I hope that was helpful :D sorry if my point got lost somewhere in there
