Best guitar solo...

[Helm]

Into the Everflow by Psychotic Waltz has some of the best double-leads ever recorded.

But technically speaking, any Behold... the Arctopus song is just one big solo and they're always impressive.

Maudlin of the Well are really impressive when their lead guitarist shreds out, but also the more reserved stuff works nice so what goes on in the end of 'A Violent Mist' is excellent. For shred madness - Gleam in Ranks.

The accoustic-then-electric solo by Matheos/Aresti in Fates Warning's 'Monument' is great.

Watchtower. Oh man. Where to start. God damn it. Almost everything is miles more advanced than most other metal, but a favourite solo is in 'The Eldritch'.

And I'm not uploading a thing. Go buy a record or two.
