I hope you enjoy this 68-word themeless. A couple of solving notes:
My favorite clues are 60 Across and 55 Down. 47 Down refers to “The Virtuoso Pianist, written by the answer. If you’ve ever taken piano lessons, you probably know this — and remember it as the stuff of nightmares. If you’ve never taken piano lessons, the answer almost certainly will be unfamiliar, but perhaps the crosses will help. My apologies for the dreck fill at 20 Down, but needs must, and just be thankful I didn’t clue it as suggested (jokingly, I think) by my astrophysicist brother: “quark components of a Sigma baryon.”
