Hey, It's That Voice!: Well it starts from Damon Albarn (the co-creator of the band and singing voice for 2-D — in essence, Albarn is the band's lead singer) and goes from there. The guest performers on some of their songs include De La Soul ("Feel Good Inc.", "Superfast Jellyfish"), Del tha Funkee Homosapien ("Clint Eastwood", "Rock the House"), Shaun Ryder of The Happy Mondays ("DARE"), Bootie Brown of The Pharcyde ("Dirty Harry"), Dennis Hopper ("Fire Coming Out of A Monkey's Head"), Bobby Womack ("Stylo"), Mark E. Smith of The Fall ("Glitter Freeze"), Mick Jones and Paul Simonon ("Plastic Beach") and Lou Reed ("Some Kind of Nature").
Named After Somebody Famous: An inversion, for singer/2D voice Damon Albarn. A manga writer in Japan decided to name his protagonist Maka Albarn after one of his favorite musicians. In the animated adaptation, her theme song is a punk-rockish, closely resembling the style of many Gorillaz songs.
So My Kids Can Listen: The exact reason why Bobby Womack came out of retirement to sing on "Stylo" (his daughter specifically nudged him to work with Albarn.) The song revitalized public interest in Womack, leading to his first album in 18 years.
According to interviews, the title of the song "Dare" came from the fact that the guest singer, Shaun Ryder, couldn't pronounce 'there' because of his accent. The original lyric was, "It's coming up, it's coming up, it's coming up, it's there!" But it was changed after a few takes proved it impossible to record that understandably.
