deLillos is a Norwegian poprock band formed in Oslo in 1984. They are generally regarded as one of the "Four Greats" in modern Norwegian pop music, i.e. one of the four 1980s groups that founded a new tradition for rock music with lyrics in Norwegian. The remaining three "Greats" are DumDum Boys, Raga Rockers and Jokke & Valentinerne.

DumDum Boys are a Norwegian rock band from Trondheim, formed in 1979 and originally known as Wannskrækk. The band is one of the most successful Norwegian rock acts of all time, and are considered one of the "big four" bands who popularized modern rock with Norwegian lyrics in the 1980s alongside Jokke & Valentinerne, Raga Rockers and DeLillos.
