how can i turn off the display without put to sleep "macbook pro with touch bar"

before i used the MBP 2011 and when i used to listen music i just turn off the screen with "Command+shif+eject disc" and the music still playing.

but now in the MBP 2017 i can find the way to only turn off the display in order to keep the music playing and save a little amount of battery and i dont want to change the display settings.
