The big part of these 100 songs are from the fathers, saints and monsters of hard rock (Led Zeppelin, Black Sabbath, AC/DC, Deep Purple, Aerosmith). You can find also the roots of hard rock (Jimi Hendrix, Cream, Steppenwolf, Blue Cheer) in the late 60s, or other artists not properly hard rock (Neil Young or Rolling Stones) in their rudest songs, one-hit-wonders (Golden Earing, Boston, BTO). Songs go from 1967 to 1979. I hope you like this torrent!
