Here’s a rainy New Year’s Eve bonus for you, merrymakers: Side D of Blue Wave Christmas, the yule-mitzvah edition of my longstanding Yuletunes Eclectic & Inexplicable series, has arrived, marking the conclusion of the most ambitious mixtape I’ve yet made. It’s long on merriment, long on obscurity, and long on length. That’s why I had to serve it to you incrementally. With this vestigal-tail chapter, some of the familiar voices from prior iterations have returned after mostly keeping mum so far this year. There are by my reckoning at least seven days of Christmas remaining, so I’ll leave you to it. You can find all four sides on this page. I wish for all of us a better 2019.
