Jeden Osiem L, a Polish hip hop group formed in 1998 in Płock by rappers Łukasz Wółkiewicz and Marcin Siwek. Their early recordings were made on simple equipment due to limited resources and lack of industry connections. In 2001, MCs Paczkos and Gmura joined. In February 2003, Gmura left the group, and later that year, Jeden Osiem L signed with UMC Records, releasing their debut album Wideoteka in 2003. The album's hit single "Jak zapomnieć" earned them nominations for the Eska Music Award and was voted Hit Single of the Year by Radio Eska listeners. In 2004, they toured in the United States. Their second album, Słuchowisko (2005), was produced under Universal Music Polska after a label switch due to creative differences.
