The fourth episode of the music series Seirm is presented by top musician and broadcaster Mary Ann Kennedy. Filmed in the atmospheric Cottiers Theatre before an audience at the Celtic Connections music festival in January 2015, this eclectic show features performances from the best of the festival alongside some unique musical collaborations.

Appearing in this episode is the acclaimed pairing of Cahalen Morrison and Eli West singing with Orkney singer Kris Drever. Another musical collaboration takes place when Karen Casey joins the McCrary Sisters, a gospel act from the United States. Closer to home we'll see the talented band Gria, fronted by Ceitlin LR Smith.
