very cool grid shape, impressive that it could fill well! liked SOURNOTES and BOYBAND, as well as the clue for ATRIA. not sure i get the clue for STABLES--do horse wrestle? one small thing--the clue for INEEDHELP is a question, but INEEDHELP is a statement. maybe something like "Give me a hand!" would work better? overall, this is a very impressive grid with some cool spanners and cool clues!
Fun entries and clues! (I had never noticed that both BOY BAND and QUINTET had seven letters. Though apparently I had noticed that *NSYNC, Backstreet Boys, and NKOTB were all quintets… even if I sometimes mix them up!)
