Top 10 Lesser Known Heavy Metal/Rock Guitar Riffs of the 70sUnlike Iron Man by Black Sabbath or Kashmir by Led Zeppelin these songs are less known .And some of the less known heaviest guitar riffs of 70s .
This is an amazing song and yes - it's very underrated. Glad to see it at #1. - Metal_Treasure
Top 10 for sure
The riff right after the intro(after the drum build-ups, also) isn't the heaviest, or in the same sense as some other bands, but it's definitely a heavy riff by a 70's rock band, never the less a Prog rock band.
