This achievement is buggy. It is supposed to unlock as a part of the story after listening to the concert near the end of Chapter 4. However, it did not unlock for me at first. After resetting before the next autosave and trying different options during the concert, still nothing.

I have not discovered a fix for this besides playing through the entire game a second time (seriously, why don't these adventure games have manual saves anymore?)

Edit: So I discovered a correlation with pausing the game during the concert or on the screen immediately after. Both times I did this, the achievement did not pop and the game controls froze. After sitting through the concert a third time (a truly riveting performance) WITHOUT pausing once, the achievement unlocked immediately after the concert finished.

As mentioned this achievement is buggy and as suggested, likely worth not pausing whilst the concert takes place.

I was able to quit out twice before the auto save but nothing. Then I waited till after the auto save, achievement still didn't unlock, so here do not leave the area and quit the game completely, restart, load back in and wait. It should pop then.
