A Sunday afternoon of live music is joining Traverse City’s fall calendar. The Alluvion Big Band’s season opener is scheduled for October 25, 2026, with doors and the bar opening at 2:30 p.m. and music starting at 3 p.m. For readers looking for an outing that does not require a late night, it is a date to keep.

A concert you can plan without an advance ticket

The official October 25 listing says no tickets or reservations are necessary and all ages are welcome. Donations are encouraged at the door, with $10–$20 suggested. That amount is a suggested contribution rather than a posted mandatory admission price; readers can plan accordingly while supporting the performance.

The distinction makes the opener easy to put on a shared calendar. There is no need to organize a block of advance ticket purchases, but it is still sensible to agree on an arrival time. Doors open half an hour before the music, allowing time to reach the second-floor room and settle in.

Who is behind the sound

The band’s own page identifies Chris Glassman as director, with artistic counsel from Bill Sears. The ensemble brings together professional musicians from across Michigan. Its published lineup includes saxophone, trumpet and trombone sections alongside a rhythm section, giving listeners several parts of the ensemble to follow.

The roster is a useful preview, but the venue notes that some members may not appear at every performance. I cannot confirm an October 25 set list from the current listing. Go for the ensemble and the season-opening occasion rather than a promised song or a guaranteed appearance by every listed musician.

For someone introducing a friend to the group, send the band page along with the date. It gives a clearer picture of the performers than a generic concert listing and supplies the upcoming schedule. The series is scheduled for the last Sunday of each month from October through May, with November 29 also listed.

Getting to the second floor

The Alluvion is at 414 East Eighth Street, on the second floor of the Commongrounds building. Its directions page explains the approaches, nearby parking and access from the garage. The venue is also close to the Boardman Lake TART Trail, with bicycle racks available at the building.

If you are taking transit, the venue identifies Eighth and Wellington as the nearest BATA stop. Check the bus service for your particular trip instead of assuming a weekday schedule applies on Sunday. For drivers, consult the venue’s parking guide and follow the current signs where you park.

The venue’s FAQ directs guests to use the elevator or stairs to the second floor and asks anyone with accessibility needs to contact it in advance. That is worth doing before concert day if you need help with seating or arrival arrangements.

A few details for the afternoon

The Alluvion says shows are general admission and encourages guests to arrive when doors open. Seating layouts vary by event, so avoid promising your group a specific table or arrangement that the opener’s listing does not confirm. If that detail matters to your visit, ask the venue directly.

The FAQ also describes nonalcoholic drinks and free water at the bar. Families can consider hearing protection for young children, as the venue recommends for infants. For a practical afternoon plan, share the official concert link, choose how you will get there and aim for the 2:30 p.m. door opening. Then keep the rest of Sunday flexible enough to enjoy the music.
