Yngwie Malmsteen (Solo) [per Pedo Bear]

Obviously most of them are in the solos with the exclusion of Eruption.

A lot of Megadeth songs have sweep picking and tapping, and like the comment before, Van Halen also has a lot of tapping in their songs. also a person called Yngwie Malmsteen does a lot a tapping, sweep arpeggios, and other very technical guitar work. Megadeth is my favorite of the 3 i told you of though
