G-Sides is a B-sides collection by Gorillaz, featuring the additional tracks from their first three singles and the Tomorrow Comes Today EP. The compilation was originally released only in Japan in December 2001. The US edition (with a slightly different track list) followed in February 2002. The European version, released in March 2002, features the original track list and the Brazilian release includes all the songs from both the Japanese and the US version. All versions have the same cover, featuring Noodle holding a skeleton doll in her hand, except for the American, Canadian and Australian versions, which have her holding a Godzilla figurine instead.
"Left Hand Suzuki Method" features a sample from "Mannish Boy" by Muddy Waters.
"Ghost Train" contains a sample from the The Human League's song "Sound of the Crowd". Also, Paula Cracker played the guitar on this track.
The Soulchild Remix of "19-2000" was featured in a commercial for Icebreakers gum, T-Online, in the Xbox game Project Gotham Racing and as a background song for intro of FIFA 2002.
