Frustration tab by Metallica

Tuning: Drop C

1st riff ? The song starts like that:
e|-------------------------------------------------------------|
B|-------------------------------------------------------------|
G|-------------------------------------------------------------|
D|-----------------------------3-2-----------------------------|
A|--3h5-55-x-3-5-3-5-6-5-3-5-3-----3h5-55-x-3-5-3-5-6-5-3------|
E|--0---00-x-0-0-0-0-0-0-0-0-0-----0---00-x-0-0-0-0-0-0-0-6~---|


2nd riff ? That?s when Lou Reed starts singing (That?s not much accurate but works fairly well)
e|-------------------------------------------------------------|
B|-------------------------------------------------------------|
G|-------------------------------------------------------------|
D|------------8--7--5--0---------------------------------------|
A|--0-xx-0----5--5--5--0---------------------------------------|
E|--0-xx-0----5--5--5--0---------------------------------------|

Then it goes to the first riff again... and then:
e|------------------------------------------------------------------|
B|------------------------------------------------------------------|
G|------------------------------------------------------------------|
D|------------------------------------------------------------------|
A|--0b2-2-2--0-2-0-2-3-2-0-2-0---------0b2-2-2--0-2-0-2-3-2-0-------|
E|--0b2-2-2--0-2-0-2-3-2-0-2-0-5-4-----0b2-2-2--0-2-0-2-3-2-0-/8~---|

And then, second riff again, before Metallica stop playing and Reed start speaking.
All this shit goes twice.
And then there is a faster riff like this:

e|------------------------------------------------------------------|
B|------------------------------------------------------------------|
G|------------------------------------------------------------------|
D|------------------------------3-2---------------------------------|
A|--3h5-5-3h5-5-3h5-5-3h5-5-3h5-----3h5-5-3h5-5-3-5-5b-br-3-5-------|
E|--0---0-0---0-0---0-0---0-0-------0---0-0---0---------------6~----|

And then

e|------------------------------------------------------------------|
B|------------------------------------------------------------------|
G|------------------------------------------------------------------|
D|--------------------------3-2-------------------------------------|
A|--5----5----5----5----5-3-----5----5----5----5-----6--------------|
E|--0-xx-0-xx-0-xx-0-xx-0-x-----0-xx-0-xx-0-xx-0-xx -6--------------|

And Then
e|------------------------------------------------------------------|
B|------------------------------------------------------------------|
G|------------------------------------------------------------------|
D|------------------------------------------------------------------|
A|-----5b-----------------------------------------------------------|
E|--0----5b5~-3-3---------------------------------------------------|
