Note: It's not perfect, but hopefully someone better than me can take a look at it and 
improve upon it. DADGAD tuning, of course.

Background tapping guitar is either
this:
D|--------------|        |---------------|
A|--------------|        |---------------|
G|-t9p5---------|  or:   |-t10p5---------|  or some combination
D|-------t10p7--|        |-------t10p7---|       of both
A|--------------|        |---------------|
D|--------------|        |---------------|

Layered guitar isn't too difficult to figure out:
|---|---|----|-----|----|----------|------|
|---|---|----|-----|----|----------|------|
|-7-|-(b9)|-10-|-12--|-14-|-14/15-14-|--17--|
|---|---|----|-----|----|----------|------|
|-5-|-7-|-8--|-10--|-12-|-12/13-12-|--15--|
|---|---|----|-----|----|----------|------|

Then I think it might be this, but then again it could've been this all along:
|--------------|
|--------------|
|-t9p5---------|
|-------t9p7---|
|--------------|
|--------------|

Clean bit at 3:50
|-----------------------------------------------------------------|
|----------------------7------7-----------------------------------|
|-(b9)---------12---------------------------------------------------|
|-------------------------------------7---------------------------|
|-------------------3------5-------------------7-------3------5---|
|---7-----10-----------------------7-------10-------3------5------|

Next part at 4:15 (this could easily be the previous bit looped over with something else 
but here it is for one guitar):
|-------------------------------------------------|
|-------------------------------------------------|
|-(b9)----(b9)-----9/12--(b9)--------9h10-(b9)--------(b9)--|
|-------------------------------------------------|
|-------------------------------------------------|
|----7-----7-------------10-10----------12-12-----|

----------------------------------------------------|
----------------------------------------------------|
----------------------------------------------------|
--------(b9)--------------------------5-------3-2-0---|
-----7----------7-7/10-0--------3-------------------|
--7--------7-----------------3----------3-----------|

then something along the lines of this:
|----17------------17---|
|-15----15-----15-------|
|-----------17----------|
|-----------------------|
|-----------------------|
|-----------------------|
but I can't really figure that bit out.
