Official music video by Summrs, for the song "test sum". Edited and shot by @r.cco. The song was produced by Eddie Gianni and it was written by him and rino himself. Test Sum is one of Summrs' most well-received tracks to date, where Slayworld’s signature ghost reverse reverb effect popularized, as many aspiring creators would look to replicate the unorthodox effect. Over 1:21 trap production by frequent collaborator Eddie Gianni, the artist raps about cars, guns & designer clothing.
