The members are the rappers Promoe (Mårten Edh), Supreme (Mathias Lundh-Isen), DJ/Producer Embee (Magnus Bergkvist) and CosM.I.C (Tommy Isacsson).

By the time they released their third cassette, From The Wax Cabinet (1996), long-time associate and frequent collaborator Supreme had become a permanent member of the group.

It was in the pre-DVSG time when Promoe and Cos.M.I.C were also part of a group of graffiti writers called the "BIF" (Babylon Is Falling) crew in Västerås.

[1] The album managed to sell reasonably well despite limited media exposure and spawned the underground hit single "Long Arm of the Law," which took a critical stance towards the Swedish police force and has since become one of Looptroop's signature songs.

Embee's solo album Tellings From Solitaria was released in 2004 and featured contributions from several notable Swedish artists, including José González, Timbuktu, and Daniel Lemma.

Looptroop Rockers worked with artists like Rakaa Iriscience of the Dilated Peoples, CunninLynguists, Timbuktu, and Adam Tensta for this album.

In late October 2014, Looptroop Rockers released their album "Naked Swedes" on CD, LP and digital formats.
