David Gilmour found the perfect balance between playing and singing, his guitar sound was our first love and gave us inspiration and hope. It is now of a past era. To continue this instrument into the future (and there is so so much more that can be with it) we need to study Joe Satriani who has explored the possibilities of it to such an incredible extent. Song structure needs to be addressed, Satriani switches keys a lot and combines a lot of techniques very effortlessly. We need to practise this. There are not enough DVD's or online lessons of Satriani on Lick Library.
