The following list details musicians who have been members of the English rock band Humble Pie.
 The original lineup consisted on Steve Marriott, Jerry Shirley, Greg Ridley and Peter Frampton.
 Frampton left the band in 1971 and was replaced by Clem Clempson who remained with them until the band broke up in 1975.
 Since 1975 there have been a number of reformations of the band including various original members and additional musicians.
 Between 1989 and 1999 original drummer Jerry Shirley obtained the rights to the band's name and began performing with new musicians, and Steve Marriott's blessing, as Humble Pie featuring Jerry Shirley.
Prime Evil is the sixth studio album by heavy metal band Venom, and the first not to feature bassist and vocalist Conrad "Cronos" Lant.
 It is also the first in a series of three albums with former Atomkraft bassist and vocalist Tony Dolan as a band member and composer.
Conrad Thomas Lant (born 15 January 1963), also known by the stage name of Cronos, is an English musician.
 He is the vocalist and bass player of the influential Thrash metal/black metal band Venom, from 1979 to 1989 and from 1994 to present.
…And You Will Know Us by the Trail of Dead (often abbreviated as Trail of Dead) are an American alternative rock band from Austin, Texas.
 The chief members of the band are Jason Reece and Conrad Keely (formerly Conrad Sobsamai).
 The two switch between drumming, guitar and lead vocals, both on recordings and live shows.
 The band is known for their wild, energetic concerts.
 Their ninth studio album, "IX", was released in November 2014.
Calm Before the Storm is the fifth album by Venom.
 The original title of the album would have been "Deadline", but the title was changed when guitarist Jeffrey "Mantas" Dunn left the band and was replaced by Jimi Clare and Mike Hickey.
 Both were to follow bassist Conrad "Cronos" Lant in his later solo career and the latter would also return on the 2006 album "Metal Black".
In music, a virtual band (also called a virtual group, cartoon group, or cartoon band) is any group whose members are not corporeal musicians, but animated characters.
 Although it mostly deals with fiction, the band itself doesn't fall under that category, as they exist outside a television and film universe.
 The music is recorded (and, in the case of concerts, performed) by human musicians and producers, while any media related to the virtual band, including albums, video clips and the visual component of stage performances, feature the animated line-up; in many cases the virtual band members have been credited as the writers and performers of the songs.
 Live performances can become rather complex, requiring perfect synchronization between the visual and audio components of the show.
Scott Sturgeon, also known as Stza Crack ( ; born March 4, 1976), is a musician who has fronted several ska-punk bands in the New York City area, the best known being Choking Victim and Leftöver Crack.
 The stage name Stza is a tribute to the Wu-Tang Clan, in which the members would take their stage names from the Supreme Alphabet of the Five Percent Nation, such as GZA (God ZigZagZig Allah) and RZA (Ruler ZigZagZig Allah) - Stza's name would therefore be "Self Truth ZigZagZig Allah".
Session musicians, also called studio musicians, are musicians hired to perform in recording sessions as well as live performances.
 Session musicians are usually not permanent members of a musical ensemble or band.
 They may accompany many singers and soloists.
 They work behind the scenes and rarely achieve individual fame in their own right as soloists or bandleaders. However, top session musicians are well-known within the music industry.
 Some session musicians form rhythm sections who make recordings together.
 Some of these have become well-known generally, such as The Wrecking Crew and Motown's The Funk Brothers.
The following is a complete chronology of the various line-ups of British extreme metal band Venom, formed in 1979.
 The group evolved out of an older group, Guillotine, formed in 1978.
 No individual has consistently remained with the group throughout its entire career; vocalist and bassist Conrad Lant, a co-founding member, fronts the group today.
Cronos were a United Kingdom-based heavy metal band formed in 1988 by Venom front man Conrad "Cronos" Lant.
