For me its headphones unless I like what is playing in the shop (we have speakers in FAI connected to the shop speakers with our own volume control. I like hard rock/metal (Disturbed, Korn, Volbeat, Slipknot, ect...)
I just watched that in the car before I walked in today! Apparently they are doing a whole live online show with the orchestra at the Royal Albert Hall. I hope they do Doomsday, that would sound amazing.
I am going to check out Crystal Lake today. I have heard good things about them but I've never listened to them.
