Artist: Green Day
Album:Insomniac
Transcribed by Graham Haworth (ghaworth@oboe.calpoly.edu)


ok, I was looking through the other insomniac album chord file, and found 
a lot of the songs weren't very accurate. So here's my version of the 
album, and I'm almost 100% sure that the chords are right, because I 
spent more than half an hour tabbing it out. I'm not gonna go into much 
detail. If you've seen the dookie_album file, its gonna be like that. All 
the chords are here, you just have to listen to the album to get the 
timing. It shouldnt be too hard. Anyway, here it is.

All songs tuned down 1/2 step. Most chords are power chords. I like to 
play D's in the open position to give it a more full sound, but it doen't 
really matter...

"insomniac"
BY GREEN DAY

This took me forever to get this on the computer. Other than that, I tabbed
the song by ear in
3omin. I was going to post on the 10th, but l just didn't have the time to
type it all out. The timing
and lyrics are probably off, because l tabbed it while l was still so fresh
to the songs, but the
powerchords are all right.

Insomniac
>From Green Day
Tabbed by.- Daniel (al640757@campus.cegs.itesm.mx)

Well here it's the entire album (all 32 minutes and 55 seconds) with no
mistakes, I hope =). I've only put the chords, if anyone thinks a TAB should
be made (with rythms, times the chords are played, etc.) just mail me and
I'll make it. Well, contrary to what most people think, I think this album is
better than "Dookie" ("Dookie" is more comercial), it's better in ...
EVERYTHING!!!!! Well, no more words, here it is.
