I´ve been listening to these Bloc Party´s so called "B-sides" lately, and I think that Selfish Son has a pretty sweet solo. But I haven´t found it tabbed here in UG.
I think it´s a combination of two guitars, at least it sounds like that to me. Unfortunately I´m not much of a tabber, I haven´t played guitar that long to be able to figure these things out yet.

So, If someone would be so nice to try, and eventually, tab the song/solo I would be grateful.
