Kathleen Callahan has seen Gorillaz 2 times.

Gorillaz is a British virtual band created in 1998 by musician Damon Albarn and artist Jamie Hewlett. Canonically speaking, Murdoc Niccals formed the band. The band currently consists of four animated members: 2-D (lead vocals, keyboards), Noodle (guitar, vocals), Murdoc Niccals (bass guitar), and Russel Hobbs (drums and percussion). Their fictional universe is explored through animated music videos, interviews, and animated shorts. In reality, Albarn is the only permanent musical contributor, and often collaborates with other musicians.
