Christopher Vondracek is bringing his piano-rock solo album, “Rattlesnake Summer: The Musical,” a musical adaptation of my 2020 poetry book to downtown Sioux Falls on Friday, Dec. 1. I’ll be at the keys, joined by the newly-formed Half-Moon Orchestra (Jared Fette on drums, Brandon Mutschler on guitar, Gerard Ahlgren on upright bass/trumpet, and sister-in-law Laura Johnson on co-vocals). We know all the songs and all the dance steps.
