Example Citation:
"In a San Diego State football T-shirt, ratty jeans and Nike cross-trainers, the tall, heronlike Herrick, the play's musical director, shuttles to and fro at the rehearsal with high-octane energy. He's an idea hamster.

Never quite satisfied, he massages the musicians to try this or that, or to just stay the hell out of the song altogether. He pushes actors to sing higher, deeper, longer, throatier notes.
—Linton Weeks, " 'Kudzu' on Stage," The Washington Post, March 8, 1998
