I have learned alot from Joe Satriani's Surfing With The Alien and Flying In A Blue Dream (the only books I have of his).
Right at the moment though I am learning Lonely In The Night by Eric Johnson.
The solos in this song are intense and it's taking quite some time to nail it.
So far from the Venus Isle book, I have learned completely SRV, Manhattan, Camel's Night Out and Pavilion. I messed around a bit on Venus Isle (the solo). Eric Johnson is just too good.
I would really love to start learning some Tony MacAlpine songs, preferably everything from Premonition, Evolution and Chromaticity. 8)
