If you’ve ever eagerly unwrapped a gift and found it filled with many other wrapped gifts, that’s the sort of Matryoshka doll experience delivered by the St. Louis Symphony Orchestra’s IN UNISON Chorus, which celebrated its 30th anniversary on Dec.13 with a sold-out performance at Stifel Theatre.

The gift-within-gift was witnessed by an audience of more than 3,000 who received a night of festive music that featured the SLSO, the IN UNISON Chorus and Grammy-winning vocal group Take 6.

The concert program showcased the chorus’s unique connection to St. Louis’s Black church community and spotlighted the unique synergy between the orchestra and the IN UNISON Chorus (always worthy of its all-cap moniker). The show highlighted – as it always does – a well-curated program of traditional holiday classics and innovative interpretations and arrangements that collectively reflect the chorus’s deep roots in gospel and spiritual music.

While Take 6 was no doubt the big-name draw for this year’s program, the absolutely most heartfelt, soul-stirring and roof-blowing performances were delivered by the chorus’ own Mary Moorehead and De-Rance Blaylock. Everything else, although excellent, was bonus in comparison.

IN UNISON Chorus member Moorehead delivered a standout, heartfelt performance of Norman Hutchins’ “Emmanuel,” richly arranged by Loehrs. Alto Moorehead’s powerful, nuanced voice commanded the arrangements layered harmonies and soaring modulations with a grounding rhythmic pulse.

Her soulful performance, paired with the arrangement’s dynamic shifts and luminous crescendos, delivered profound emotional depth to this classic, capturing the power and intimacy of its message. Her moving rendition was exceptional for its emotional authenticity and reverent energy.

During the second half of the program, IN UNISON Chorus member Blaylock belted out a stunning performance of Walter Hawkins’ “Thank You,” a gospel masterpiece that expresses profound gratitude for divine grace, blending heartfelt lyrics with a lush, uplifting arrangement. As arranged by Cymbalta, this version introduces dynamic shifts and intricate vocal layering to enhance the song’s emotional resonance and spiritual fervor.

This song and arrangement exemplified why the IN UNISON Christmas concert perennially stands prominently in the St. Louis calendar of holiday entertainment. It’s always noteworthy for the performance as well as the curation of the richly varied program by conductor and chorus director Kevin McBeth and the SLSO’s artistic team, especially the inclusion of lesser known compositions, especially for those not immersed in the world of gospel and spiritual.

Backed by the chorus, alto Blaylock truly earned the tag showstopper with her performance of “Thank You.” Blaylock’s intense performance soared effortlessly above the choir’s richly textured harmonies and the arrangement’s dramatic crescendos. That combination created a powerful blend of intimacy and exaltation.

Also impressive was the wide range of ways she projected the two words – thank you – to deliver new and expanding meaning to the song’s message. Blaylock’s performance was so emotional, moving and powerful that it earned its own well-deserved (one-verse) encore.

The concert opened with an orchestral rendition of “Joy to the World,” which set a jubilant tone, then the chorus joined for Dan Forrest’s “Gloria in Excelsis” from “LUX: The Dawn from On High.” This song was a dazzling choral and orchestral celebration of light and divine glory, and indicated the level of performance promised by the rest of the program.

Among the pleasing mix of works, the program reprised a crowd favorite – Handel’s “Hallelujah” chorus, a song composed for Easter celebrations that has nonetheless elbowed its way in the Christmas repertoire. This program delivered the Warren/Jackson/Kibble/Hey/Chinn arrangement made famous in the Grammy-winning 1992 album “Handel’s Messiah: A Soulful Celebration.” McBeth paid tribute the producer of that album – Quincy Jones.

McBeth introduced Take 6 as “those jazzers” and announced this was the fourth time the group had collaborated with IN UNISON. Midway through the first half, the a cappella group jingled, jangled and jazzed their way through Christmas favorites, including a swing version of “Do You Hear What I Hear” in their defining style.

As the master showmen that they are, Take 6 could have carried an entire show all by themselves, yet they wove their songs into the program as seamlessly and tightly as their harmonies. The group returned in the second half to light up the final segment of the concert. Their humorous take on Tchaikovsky’s “Dance of the Sugar Plum Fairy,” which they titled “Sugar Plum Dance,” was a tasty aural treat with inventive vocal mimicry of orchestral instruments.

A Celebration of Tradition and Innovation

This year’s IN UNISON Christmas concert was a powerful reminder of the chorus’s enduring impact over three decades. Founded in 1994, the SLSO’s IN UNISON Chorus brings together talented volunteer singers from more than 30 local Black churches. Since then, it has become a vital cultural institution, blending community traditions with musical excellence. This year’s IN UNISON Christmas concert honored its enduring legacy with a joyous celebration of faith, collaboration and the transformative power of music.
