San Francisco band Blue Cheer release one rough and distorted cover of Eddie Cochran classic "Summertime Blues", from their 1968 debut album Vincebus Eruptum, wey outline much of di later hard rock and heavy metal sound. Di same month, Steppenwolf release their self-titled debut album, wey include "Born to Be Wild", wey contain di first lyrical reference to heavy metal and help popularise di style when e dey used for di film Easy Rider (1969). Iron Butterfly's In-A-Gadda-Da-Vida (1968), with its 17-minute-long title track, wey use organs and with a lengthy drum solo, also prefigured later elements of di sound.

From outside di United Kingdom and di United States, di Canadian trio Rush release three distinctively hard rock albums for 1974–75 (Rush, Fly by Night and Caress of Steel) before dem begin move towards a more progressive sound with di 1976 album 2112. Di Irish band Thin Lizzy, wey form for di late 1960s, make their most substantial commercial breakthrough for 1976 with di hard rock album Jailbreak and their worldwide hit "The Boys Are Back in Town", wey reach number 8 for di UK and number 12 for di US. Their style, wey consist of two duelling guitarists wey dey often play leads in harmony, prove say e be large influence on later bands. Dem reach their commercial, and arguably their artistic peak with Black Rose: A Rock Legend (1979). Di arrival of Scorpions from Germany mark di geographical expansion of di subgenre. Australian-formed AC/DC, with one stripped back, riff heavy and abrasive style wey also dey appeal to di punk generation, begin to gain international attention from 1976, wey culminate in di release of their multi-platinum albums Let There Be Rock (1977) and Highway to Hell (1979). Also influenced by one punk ethos na heavy metal bands like Motörhead, while Judas Priest abandon di remaining elements of di blues for their music, further differentiate di hard rock and heavy metal styles and help to create di New Wave of British Heavy Metal wey dem pursue by bands like Iron Maiden, Saxon and Venom.
