For once I seemed to be on Mr. Sternberg's wavelength. I blundered my way into this one by guessing "Kazakhstan" for TAJIKISTAN (5A: Land bordering western China), and then I kind of backed into the puzzle from the NE. I guessed that 16A: Like the Hulk, typically" might end in "rage" (ONARAMPAGE), which helped a little - until it didn't. I love that clue and answer, by the way. And luckily, "Kazakhstan" has a K in the same place as TAJIKISTAN, and I was able to get KALEL (9D: Infant rocketed to earth from Krypton) off of that.
The grid is reminiscent of yesterday's, with it's tall triple stacks in the NW and SE, but is much more open overall, with good flow from one section to the next. The stacks are all decent. For some reason, of the two brand names, I prefer ELECTROLUX (60A: Hoover competitor) to KIASORENTO (32D: Toyota Highlander alternative). Is it because ELECTROLUX is an older brand? Or because Kia misspells Sorrento? Much like Toyota misspells Siena. Or are they not trying to evoke Italian towns with those names? Who knows? Certainly not me.
Anyway, this one breezed by, perhaps a bit too easily. There were some straightforward clues that were tough for me - I was not familiar with DELIBES (58A: "Sylvia" ballet composer, 1876), and I didn't remember SILAS (53D: Monk in "The DaVinci Code"), for example, but the clues that seemed like they were meant to be tricky were not so today. 17A: One having a ball at the circus (SEAL), 27A: Checked out like a wolf (OGLED), 36A: "Baa! Baa! Baa!" singer (YALIE), and even 49A: "B.C." sound effect (ZOT) went right in.
Overall, a lovely grid, and a solid puzzle.
