I started practicing trumpet w drones a couple years ago, relying on YouTube for tracks, and just recently found these ones. It's a fantastic way to get away from time and speed and just concentrate on tone, focus, breath control, interval tuning, and Zen.
Andy Shauf's writing is just jaw-dropping. I'm listening to this new record for a seventh time in a row. Every record he does is an end-to-end narrative, and here he has somehow outdone himself yet again: the writing is simultaneously clever and casual, with sparse arrangements that are pristine and immaculate. This is a high water mark of musicianship.
