Porcupine Tree – Bonnie The Cat
From The Incident (2008)

Dropped D Tuning DADGBe

/ = slide to
\ = slide from
h = hammer-on
p = pull-off

Usually I’m pretty strict about bar-durations and note-lengths 
(bar being |----| and note lengths being just --- in between) 
but for the convenience (of reading and creating the tab) I just did it loosely this time.   

Intro synth (also played during verse)

Yes, this ^ riff is pretty damn hard to play. Live they play the riff below all the time. 
I think that part is just for the record and played in standard tuning.
