Combo Carols - Meet the Players

Meet H3O’s friends and family who brought our holiday album to life

Eric Heukeshoven, piano & keyboards

Hans Heukeshoven, drums & vibes

Hans double-majored in percussion performance and computer science.
He is a successful software engineer who continues to pursue his passion in music playing with H3O and teaching the next generation of musicians.
He’s also the father of Felix and Fiora, Eric & Janet’s two grandkids.



Max Heukeshoven, bass

Eric began playing professionally at age 15 with the Dixie Ramblers in Moline, Illinois. After 35 years of college teaching Eric became Director of Worship, Music & Arts for Central Lutheran Church in Winona, Minnesota. He holds music degrees from Indiana University and the University of Minnesota.

Max will be the first to tell you that his dad made him choose the bass when he was young. Whether or not that’s true, Max is an incredibly talented player with the ability to know where a song is going even when he’s never heard it before.


John is a fixture of the Rochester, Minnesota music scene. In addition to his own groups, The D’Sievers and Loud Mouth Brass, he can be found playing with area groups like The Soul Train and Jaggedease on any given day. When not making music (which is rare), Dr. Sievers teaches in the English department at Rochester Community and Technical College.





Janet Heukeshoven, flute

For many years, Janet’s repertoire was strictly classical – then she decided to learn to improvise and play jazz. After a career spanning more than 30 years as a dedicated professor of music, “Dr. H." now has time to work on her jazz chops. When she performs with the trio they call it “H3O+mom."


John Paulson, sax & flute

John Sievers, trombone

Brett Huus, audio engineer

Master of his craft, Brett is a Grammy Award winning audio engineer. A talented musician in his own right, Brett owns and operates SoundStrations Studios in La Crosse, Wisconsin. You would not be listening to either of H3O’s albums had it not been for the skill and experience Brett brought to our projects.



Snooky Larson, valve trombone

Snooky makes a cameo appearance on Swingin’ Kings. A longtime friend of H3O, Snooky has been swingin’ on trombones of all shapes and sizes for as long as anyone can remember. Snooky is almost family, but doesn’t like to be in photos.

Dr. John C. Paulson is Professor Emeritus from Saint Mary’s University where he taught for 32 years. After his retirement, he formed the John Paulson Big Band. The group is dedicated to playing John’s original jazz compositions. He is also the godfather of bassist Max Heukeshoven.

Terri Lieder, graphic designer
