Podcast Episode # 49 Karl Tirén: Composing, Band Leadership & Overcoming Injury

Join Magnus Zetterlund as he sits down with Swedish mandolin player, bandleader, and composer Karl Tirén to discuss his innovative Atlas project—a unique trio featuring mandolin, trombone, and double bass. Karl shares his compositional process, the journey from injury to inspiration with the tune "At Last," and how he practices through playing rather than drilling scales.
