Favorite/Best all time Riffs
 

What is everyone's favorite riffs or riffs that they just think are the best?

-Excluding vocals, drums, bass, etc. and just focus on the riff. And it can be any type of genre, not just metal.

Dunno bout favourite will have to think about it, Sooo many... but a couple I've always loved are that Bit that comes after chorus in Primal Concrete Sledge. Intro to Crazy Train. Everything Jack White plays on Jolene. Gimmie shelter.

first one that springs to mind for me is acdc - beating around the bush. that's definitely one of my favs, there will be loads more but I'm still half asleep so brain hardly workin

Are we talking about just riffs or extended guitar solos here? Not being a musician of any type, for me a riff is just a brief guitar piece that repeats itself over the course of the song at different stages whereas I see a guitar solo as forming an entire section of the song, anyway whether they are riffs or solos some of my favs over the years are:

Smoke on Water-Deep Purple
Celebration Day-Led Zeppelin
Whole Lotta Love-Led Zeppelin
Purple Haze-Jimi Hendrix
All Along the Watchtower-Jimi Hendrix
Hydra-Toto
Edge of the Blade-Journey
Walk-Pantera
Sunshine of Your Love-Cream
Under the Bridge-Red Hot Chilli Peppers

Also there is an amazing guitar solo by Rich Williams of Kansas on the Masque album but can`t think of the name of the song.

War Pigs. Seconding the Crazy Train nom above. Paperback Writer. Back in Black. Jumpin' Jack Flash. Superunknown, from Soundgarden.

This is almost impossible

Octovarium- Dream Theater @ 3:49 (I know it's not technically a riff,)
Welcome to the Jungle- Guns 'N Roses
Knights of Cydonia- Muse
All Along the Watchtower- Jimi Hendrix
Electric Tears- Buckethead
Ride On- AC/DC (simple, yet awesome)
Smells Like Teen Spirit- Nirvana

and so many others

Electric Wizard - Funeralopolis (The main riff)

Perhaps not the best, but ZZ Top's La Grange certainly springs to mind :D

Whiskey in the Jar- Metallica.
Love that song.

Forgetting the riff, I actually prefer the original Thin Lizzy version.
