Smooth, seductive, sweltering and sultry are just some of the words (beginning in S) used to describe singer-songwriter Karyn Kirkwood. Kirkwood was the co-creator and lead singer for the popular Guelph-based quarter Indigo Riff.  The quartet played regularly in the Guelph area for six years, recording a full-length CD of original tunes played on CBC Radio.  Known for her engaging live show, Kirkwood is a natural with the audience. She will be joined by musical riff-raff Jeff Daniels (piano), Dave O’Neill (drums), and Jesse Turton (bass).
