Question: Who is musician, filmmaker, and screenwriter, Pete Loeffler or Rob Zombie?
Context: Chevelle is an American alternative metal band that formed in 1995 in the Chicago suburb of Wildwood, Illinois.  The band was originally composed of brothers: Pete Loeffler (lead vocals and guitar), Sam Loeffler (drums and percussion) and Joe Loeffler (bass and backing vocals).  When Joe left the band in 2005, Geno Lenardo subbed-in as the bassist until he was replaced by Pete and Sam's brother-in-law, Dean Bernardini. Pete Loeffler (born October 19, 1976) is a musician, known for his work with the Chicago-area rock band Chevelle, for which he is the lead vocalist and sole guitar player. The Electro-Industrial Tribute to Rob Zombie is a tribute album completely dedicated to heavy metal musician Rob Zombie.  It contains the original song "Dealt With" inspired by Rob Zombie's music. "Letter from a Thief" is the second single from Chevelle's album, "Sci-Fi Crimes".  It was released on December 7, 2009.  Chevelle originally debuted this track on April 9, 2009 at a concert in Atlanta.  Frontman Pete Loeffler said the song is about a personal experience for the band when their gear was stolen in Dallas, and his prized red PRS guitar seen in the video for "Send the Pain Below" was stolen, along with the rest of the band's gear, and returned by a man in California who returned the guitar to PRS after learning it was Loeffler's. Rob Zombie (born Robert Bartleh Cummings; January 12, 1965) is an American musician, filmmaker and screenwriter.  Zombie rose to fame as a founding member of the heavy metal band White Zombie, releasing four studio albums with the band.

Mondo Sex Head is a remix album by Rob Zombie, containing remixes of the tracks of various past albums both by Zombie and his former band White Zombie.  It was curated and executive produced by Jason Bentley.  The original cover art depicted Zombie's wife Sheri Moon Zombie.  It caused controversy and was replaced by the image of a cat.  Rob Zombie explained, "I never thought it would be a problem since it seemed tame to me... but it was.  No one would carry the CD.  Anything with death and violence is totally fine, but anything with sex, forget about it.  So instead of censoring that cover and ruining it, I just removed the ass shot and replaced it with a pussy shot."  Though the vinyl release remained unchanged with the original cover art. "Superbeast" is a promotional single off Rob Zombie's solo debut, "Hellbilly Deluxe".  The song was co-written by Charlie Clouser, formerly of Nine Inch Nails.  It also appears on Rob Zombie's "Past, Present & Future", the greatest hits album "The Best of Rob Zombie", and two remixes are contained on "American Made Music to Strip By".
