How does Brian "build" his guitar solos?

I've played the guitar since '95 and Brian is one of my biggest influences (along with Gustavo Cerati) and I've always been in awe of what Brian can do live, in terms of throwing new ideas to different solos. He's always very aware of the harmony of the song and builds from that, not going in rambling scales and chops (like Dave Murray). He's mixing licks with little nods to the riff, and using the delay to harmonize with himself, specially if the song has no piano or keyboards. The trio sound can become very flat if the guitar player goes off on his own.

He's also trying to find new melodic lines to parts of the song that already had a melodic line, sung by Freddie or played by another instrument. Somebody to Love is a good example, he's "singing" over the verse.

I really like to listen to the different versions of the final solo in A Kind of Magic, in the 86 tour. With all those years of playing live, he's got all the confidence to let himself go in some wild impro, giving the song a boost at the end.

Excuse me for my poor english, but I love to talk about guitar playing.

One thing about Brian's playing, and I'm sure i've seen this spoken about before somewhere, is one of his regular little traits is to solo slightly behind the beat, especially on bends.
