Tuesday: When you put Philip Brunelle and Garrison Keillor together, you never know what's going to happen. Their twisted senses of humor and collective creativity collide in "Gratitude, Gravy & Garrison," VocalEssence's celebration of all things Thanksgiving. Keillor performs his signature monologue and contributes comic new lyrics to familiar songs and hymns. He also supplies the lyrics to "Table Grace," one of two world premieres by Los Angeles-based composer Matthew Brown. Jazz vocalist Jearlyn Steele and pianist Rich Dworsky add their talents to the musical mélange. (7:30 p.m. Tue. $28.50-$53.50. Orchestra Hall, 11th St. and Nicollet Mall, Mpls. 612-371-5656.)WILLIAM RANDALL BEARD
