Especially the drums in a rock band. But take it away, and you really feel the absence. Just like the bass I guess.
My favourite Stones songs are Wild Horses and Angie, but Get Off My Cloud and Satisfaction have some great drumming by Charlie Watts.
A few lines from Shine a Light seem appropriate:
'May the good Lord shine a light on you
Make every song your favourite tune
May the good Lord shine a light on you
Warm like the evening sun'
RIP, Charlie Watts.
