In the spirit of celebrating the rock drummer, I give you (in no particular order) Great Drum Fills, Pt.1:
Drummer: Keith Moon
Group: The Who
Album: Who's Next
Great Drum Fill: (It's Keith fucking Moon, do you need a fucking list?!?!) In "Baba O' Riley", after the lines "Don't cry, don't raise your eye, it's only teenage wasteland", Keith Moon (official Kyklops-sanctioned rock "god") blats out a drum fill that will live forever in the annals of rock.
[Updated 10/4/13: You'll find the drum fill at the 2:30 mark of the clip below.]
