I was pleasantly surprised with the sim sessions

I enjoyed it much more than I thought I would! Love the bow and audience acknowledgement animations - they were a nice touch. My son was a bit wierded out by the unexpected-to-him Simlish acoustic version of Bebe Rexha's song :D But he's not a Simmer. Really, all I'd want more is a second song from each artist. And for the after-concert performances to please prioritize Sims with skills next time this is done.

@foxybilly I thought it didn't spawn at first too, but it's off in a farther corner, IIRC to the upper right of the more used part of the park. I suspect it's an uneditable area.
