Humble Pie are an English rock band formed by former Small Faces vocalist and guitarist Steve Marriott and former Herd vocalist and guitarist Peter Frampton in Moreton, Essex, in 1969. The original line-up was completed by former Spooky Tooth bassist Greg Ridley and former Apostolic Intervention drummer Jerry Shirley. They are known as one of the first supergroups of the late 1960s and enjoyed success in the early 1970s with songs such as "Black Coffee", "30 Days in the Hole", "I Don't Need No Doctor", "Hot 'n' Nasty" and "Natural Born Bugie". Frampton left the band in 1971 and was replaced by Clem Clempson.

Spine of God is the debut studio album by American rock band Monster Magnet, released in Europe in 1991 and in the United States the following year. The album represents one of the earliest examples of the emerging 1990s sub-genre of stoner rock. Spine of God did not perform well commercially upon its initial release, but was praised by critics and would later be considered a major influence on stoner rock bands. The song "Medicine" was released as a single with accompanying music video.

Hard rock or heavy rock is a heavier subgenre of rock music typified by vocals and electric guitars that are aggressive and distorted relative to traditional rock music. Hard rock began in the mid-1960s with the garage, psychedelic, and blues rock movements. Some of the earliest hard rock music was produced by the Kinks, the Who, the Yardbirds, the Rolling Stones, Cream, Vanilla Fudge, and the Jimi Hendrix Experience. In the late 1960s, bands such as Blue Cheer, the Jeff Beck Group, Iron Butterfly, Led Zeppelin, Creedence Clearwater Revival, Golden Earring, Steppenwolf, Grand Funk Railroad, Free, and Deep Purple also produced hard rock.
