Virtual band: 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.

Stza: 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 musician: Session musicians, also called studio musicians, are musicians hired to perform in recording sessions as well as live performances.

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.
