Throughout the puzzle there was a real TANG to the cluing including some excellent QMCs like "Keep bumping into another punk music fan? (MOSH), "Place for a royal flush?" (LOO) - ha! - and "Wreck room?" (STY). DIDO for the non-QMCs like "Spot for a guard at the World Cup" (SHIN)
"Gathering where one might make a splash" (POOLPARTY), and "Puts on" (DONS).
As if that weren't enough, we were treated both to quality words in the clues themselves like akimbo, stampede, and cavernous, and fine fill such as ASTUTE, MALADROIT, and CUSP. Plus Tupperware (LIDS)! A nice flourish was the C/AP pair "Not supporting" (ANTI) and "Supporting" (PRO), the latter of which, in case you haven't guessed it already, describes my stance vis-à-vis this puzzle. :)
