This fella is our musical director. Jeremy grew up just north of Sioux Falls in cozy Dell Rapids. He graduated from Augustana College and now teaches at the new Augustana University School of Music. Early on Jeremy became fascinated with complex musical arrangements featuring many layers, especially the addition of horns. This helped lead to the 9 piece horn band Spooncat! that has played throughout the region since late 1996. The opportunity to create a holiday ensemble in a similar fashion was too hard to resist.

His early days of playing led to fun opportunities to back up legendary performers such as Smokey Robinson and Chuck Berry among notable others. In 2003 he received the Mayor’s Award for Performing Arts. The arranging bug isn’t just for his own projects as he’s been the pen behind numerous high school marching band shows and collegiate and professional ensembles. He has composed pieces for symphonic band and did a commission from the Omaha Symphony in memorial of the tenth anniversary of 9/11. Recently he was awarded the inaugural Outstanding Musical Alumni award along with fellow Holiday Jammers, brother Jon and Andrew Reinartz.


Jon is the youngest of three musical sons whose parents were music educators. At this point he’d like to point out the artwork for the show this year was done by his older, middle brother Jason. So it’s sort of a family affair.

Jon has also played in Spooncat! and done his fair share of backing up famous acts from the past. He once shared a stage with the original Comets who backed Bill Haley. So if you’re wondering whether rock and roll started with Chuck Berry’s “Johnny B Goode” or Bill Haleys’ “Rock Around the Clock”, well it’s technically neither. But it sure is fun to have a slight connection to an art form that is still young enough for us to have had the honor of performing with them.

Along with a smattering of stints teaching and arranging music, Jon’s preference is to play with music behind the scenes, making the albums for the various groups he’s in with Jeremy, a hobby that shows off his olympic ability to sit around at his home for hours on end.
