Gotta Go - Agnostic Front (tabbed by: ryan b) 

This is a great song to play, and it has a lot of weird fills and scales placed in it 
throughout the whole song.  My best advise is to experiment with fills, 
and basically improvise them throughout the song (or use the fills I've suggested). 

Riff A: (3 times)"From the East Coast..." 
A--------------------5------------------ 
E--0--------3-----------------0--------- 

Riff B: (5 times) "Don't believe what..." 
A--------------------55555555----------- 
E--00000000-33333333----------00000000-- 

Riff C: (5 times)      "Say I'm crazy..." 
A--------------------5---5-------------- 
E--0---0----3---3-------------0---0----- 

Riff A: (twice) 
Riff B: (4 times) 
Riff C: (5 times) 
Riff A: (twice) 

Riff A: (9 times) 

Riff D: (once) 
A--------------------55555555----------- 
E--00000000-33333333----------0-----00-- 

BASIC FILL #1: 
Occasionally on Riff B/Riff C, the bass will cut the final E notes (open E) 
short, and play it only four times instead of eight. This fill is then added: 
G----------- 
D--7--5----- 
A--------7-- 
E----------- 

BASIC FILL #2: 
As with Basic Fill #1, the bass (during Riff B/Riff C) will cut the final E notes 
(open E) short, and will play them four times instead of eight.  Basically the 
reverse of BASIC FILL #1 is then added: 
G---------- 
D-----5h7-- 
A--7------- 
E----------
