ANY song by tool.... and of course the led zeppelin ones you named above are also very good. Purple haze and voodoo child are also great riffs
TOOL9 Reviewed by TOOL9 on . Favourite riff in rock music Any rock fan knows the definition of a musical riff. "Heartbreaker" by Led Zeppelin features an amazing riff by Jimmy Page, as do "Immigrant Song", "Whole Lotta Love", "Over the Hills and Far Away (acoustic riff), etc. Joe Perry's riff in "Sweet Emotion" is also very enjoyable. A great bass riff can be heard from Roger Waters in "Money" (Pink Floyd)... Tell me your favourites! Rating: 5
