Also the solo in Priest's Beyond the Realms of Death.
Schenker's Rock Bottom solo on Strangers in the Night.
(Just for Grendel) Rothery has some decent tone, can't think of anything off hand that stands out, but guess the stuff on Gaza ain't bad.
(does it count as a solo if they draft in Steve Howe for the Spanish guitar?) but add that and Brian May's solo on Innuendo for a not bad effort.
Buck Dharma's effort on Astronomy.
Peter Green's bit on the Green Manalishi... is still highly disturbing. Not sure Oh Well counts for this type of thread, but I love the second part of that.
