Lonesome blues

Taking my Benjamin out for a treat we drove into this carpark where saxophone and orchestra were heard out loud. Soon we discovered this man playing his sax and having a soudtrack in his boot as back-up.
He was full in his coccoon and didn't noticed my blipping gestures. So, I don't know why he played his tunes out there; cause he wanted to be heard & seen or was it to avoid clashes with his wife, his neighbours?! He was playing here still when we came back to pick up our car some 2 hours later...
