Here's a really cool lick from Al that also doubles as an excellent alternate picking exercise. You can tell that Yngwie definitely listened to Al quite a bit I think... The thing that Al is really good at is lighting fast alternate picking while his right hand mutes the strings leading to a very staccato attack. I grabbed this lick from Al's "Race with the Devil on a Spanish Highway" which is full of killer speed licks. I highly recommend any aspiring shredders to give that track a listen, or in fact anyone that just wants to improve their alternate picking. The tempo is pretty frightening ..so slow the track right down with whatever software you like ( I'm a big "Transcribe!" fan) and work towards getting his level of articulation when playing fast. The lick sounds like this looped: http://www.box.net/shared/sj4ty36ocl ..and looks like this: Try moving the whole lick around all over the fretboard whilst keeping time with a metronome. It's a GREAT picking workout!. Have fun!
