Wonderful early-week theme. You'd think that a musician with a 25-year history of playing in orchestras, jazz bands, symphonies, string quartets, etc. would pick up on instruments hidden at the ends of theme phrases. Only a dunderhead would say YES, I KNOW THIS THEME; IT'S GEOMETRIC SHAPES!

Bah. CHAMPAGNE FLUTES are cylindrical, and I stand by that fact. Er, "fact."
But TAPE RECORDERS ARE RECTANGULAR BOXES!
Maybe I shouldn't comment on SEX ORGANS.
If only the gridwork had been as strong as the theme. Take that southeast corner, for example. Parallel placement of a themer and a revealer, squished together in one corner, rarely works out. You never want to subject newer solvers to something like INRI. These types of "I have to know THIS if I want to do crosswords?" entries are no good, hearkening back to the days of Maleska taking smug pride in making crosswords esoteric. Sure, the crossings are fair, but it's still not a fun entry for most people to encounter.
As much as I enjoy having a revealer in the "omega position" (the final across answer), I'd much rather give up some elegance to preserve a better solving experience. Shifting MUSIC all the way to the left might have helped, but that, of course, would require a complete grid redo.
It's such a shame that Alex and Queena's intent didn't align with Will Shortz's vision. I prefer Will's approach — the delayed a-ha is fantastic — but shooting it back to the constructors would have resulted in a much more polished grid. That's a big ask, given how many puzzles Will has to churn through, but even if he had to hire another assistant to get this done, it'd be well worth it.
There are benefits to this audacious grid layout, no doubt. I love the word CHICANERY, and to get so much CAN OPENER, PIN SETTER, BREXIT? OK, I'LL BITE! If the theme had been harder, more like Wednesday or Thursday difficulty, I'd have happily given the thumbs-up.
Other solvers without a pesky constructor's voice in their head might have a stronger solving experience. There is something to be said about some Tuesdays pushing boundaries, after all. Such a shame (that I can't get past my insistence on technical excellence), as the theme was POW! quality.
