Look for Dr. Kirby Shaw, arranger extraordinaire and presenter at the International Youth Barbershop Chorus Festival at the Midwinter Convention. Kirby is an accomplished musician, conductor, writer, arranger, improv artist, and teacher. He's a staple at many ACDA events, often leading interest sessions and reading sessions with characteristic wit and charm.
If you're in New Orleans, you can thank him in person for the newest arrangement, "Shut De Do." Influenced by the classic spiritual style, this one is energetic, fun to sing, and has solo opportunities and an irresistible groove.
Oh, and while you're at the website, don't forget to look for Kirby's arrangements of Cups (now available in TTBB, SSAA, and SATB voicings) and I'm Yours.
