Our November edition of "Heavy Rotation" includes new favorite songs from public-radio stations across the country. Starting out west, Colorado Public Radio's OpenAir channel highlights one of Denver's most promising young voices, Esme Patterson. Kansas Public Radio's "Trail Mix" show is obsessed with folksinger Rayna Gellert. WEMU in Ypsilanti, Mich., is feeling blues belter Mary Bridget Davies. WXPN in Philadelphia recently added the wonderfully named Foxygen. And Vermont Public Radio is getting ready for winter with bassist Marcus Miller.
