Thistle Sifter is an ambient instrumental post-rock project by English musician Pete Barnes (Utrecht, NL). 'Circles' is based on a serious cycling accident that literally catapulted Barnes into disarray in November 2020. Written during an extended recovery period and far from family & friends in England, Circles is inspired by personal struggles with health, acceptance and letting go of the past. Post concussion syndrome symptoms forced Barnes to live a secluded life out of necessity, and during this time music became the ideal therapy. The result is a powerful ambient instrumental record inspired by Brexit, Covid and the difficult, ongoing path to Barnes recovery.
