So many to choose from. I can't really link a video, since it was at a concert I went to, but Foo Fighters slapped a big old solo chain into Stacked Actors that was amazing.
As for recorded albums, there's the always popular Stairway, obviously. It's timeless. I also enjoy the solos in The Darkness' first album, Permission To Land. It's hard to choose one, but I'd go with I Believe In A Thing Called Love. Also, it's not a solo but the main riffs in Justin Hawkins' new band Hot Leg's song I Met Jesus are tasty.
