Calum Stewart is very active these days playing as part of the Scottish group Manran. He is fully booked with events like Samso Festival( July 20, Denmark with Manran), Spyfest (July 28 Moray, Scotland with Heikki Bourgault), and also on July 28 at the same venue with Manran.
This short video caught my attention because of this unique glass whistle. I haven’t seen anything like it.
