The Who--Baba O'Reilly
Starts out on a synth, but using two guitars:
Guitar 1: x-8-10-10-x-x eadgbe
Pick quickly A-A-D-D-G-G-D-D-A-A-D-D-G-G-D-D (all 1/16th notes) over and over
(Technically, this is until the end of the song, when the violin comes in.)
Guitar 2: x-x-x-10-13-13 eadgbe
Pick quickly G-G-B-B-e (G and B strings played as 1/16th, the e is an eighth)

the drums and bass enter. The piano and bass play a simple F-C-Bb
For guitar in place of piano, it is played
F x-x-x-5-6-5 C x-x-x-5-5-3 Bb x-x-x-3-3-1
The first verse is played the same way:
