Over the weekend I tuned in, more than once, to the YT channel, Richard McVeigh | Beauty In Sound. He played all the Hymns from a newly published Hymnal (741 hymns), on organ, for 28 straight hours with a few 10 minute breaks. It was broken into 3 live streams because apparently there's a 12-hour limit on single streams. It was pretty awesome. I like listening to the music of hymns, especially on organ. He did it as a fundraiser for his crowdfunding of a new semi-public music performance space. I especially enjoyed the overnight session, which ended up in the 2nd video. It was quiet, peaceful, and lovely. This is the 2nd video, the 1st and 3rd are easy to find.
