Formed in Stockholm by childhood friends Adam Olenius (vocals), Ted Malmros (bass), and Carl von Arbin (guitars), Shout Out Louds found an international audience during the early 2000s with their peppy Swedish pop. The lineup began taking shape in 2001, with drummer Eric Edman and keyboardist Bebban Stenborg climbing aboard shortly thereafter. Shout Out Louds wasted little time writing songs, the first three of which formed the basis of their first demo tape. The music caught the ear of Filip WilÚn, owner of Sweden's Bud Fox Recordings, and he quickly signed the group to his label. Shout Out Louds then spent the majority of 2002 writing more songs, and December found them recording their debut EP, 100░, which was released in 2003. The group's high-energy, ultra-melodic sound was in place from the very beginning.
