Kantorei, Inc.

What Kantorei, Inc. does

Kantorei, Inc. is a private nonprofit arts organization operating an a cappella chamber choir based in the Minnesota Twin Cities. Founded in 1988 by Axel Theimer, the organization is currently in its 38th season and maintains an audition-based roster of approximately 45-50 singers organized into four classical voice sections (Sopranos, Altos, Tenors, Basses). Its core product is live choral performance: the ensemble typically presents four seasonal concert programs per year, anchored at Augustana Lutheran Church in St. Paul. Beyond live concerts, Kantorei runs a New Recording Initiative that has produced three albums since 2023 — 'Missa Brevis: The A Cappella Choral Music of Hyun Kook' (March 2023), a Jonathan Posthuma album (March 2024), and 'From Such Sparks: Choral Music of Gerald Cohen' (2024-25 residency) — distributed via Bandcamp, Apple Music, Spotify, and YouTube.

The organization's business model combines three revenue streams: ticket sales at $25 per concert, recording sales and streaming royalties, and tax-deductible charitable donations solicited through its website. The organization is governed by a Board of Directors and led by Artistic and Managing Director Adam Reinwald (appointed 2021), with Founder Axel Theimer serving as Artistic Director Emeritus and Tony Rangel as Assistant Conductor. There are no institutional investors, parent entities, or venture funding; the organization operates as an independent nonprofit domiciled in Minnesota. Marketing and audience development run through kantorei.net as a central hub, a GDPR-compliant email newsletter, social media, and digital streaming platforms. The organization distinguishes itself through an emphasis on vocal health, a globally curated a cappella repertoire spanning well-known and emerging composers, and composer residency partnerships that feed its recording pipeline.

• VocalEssence: Long-established Twin Cities choral organization founded in 1969, presenting choral concerts, educational programs, and community singing initiatives. Competes with Kantorei for the same Minnesota audiences, donors, and singers.
• Cantus: Twin Cities-based professional male vocal ensemble specializing in a cappella repertoire. Directly comparable in mission, repertoire focus, regional base, and personnel overlap — Adam Reinwald spent nearly two decades with Cantus before joining Kantorei.
• Chanticleer: San Francisco-based Grammy-winning a cappella vocal ensemble performing a similar mix of historical and contemporary choral repertoire. Closest national analog in ensemble size, a cappella focus, and recording/touring model.
