In the mid-1970s Syrjä formed the band Eppu Normaali in Ylöjärvi together with his older brother Mikko "Pantse" Syrjä, their cousin Aku Syrjä and school friends, rehearsing in a small outbuilding on the family property that became known as the band's first practice space.[5] The band began as a punk and new wave band in 1976 and made its first public appearance at the Rockin SM competition in 1977, where it received an honourable mention.[6]
During the early 1980s Eppu Normaali's musical style evolved from fast, raw punk towards more melodic rock and pop while retaining an ironic and narrative approach to lyrics, and the band grew into one of the most popular and influential Finnish rock groups.[1][5][6] Eppu Normaali has remained active for several decades, and its 40th anniversary in 2016 was marked by a sold-out concert at Tampere's Ratina Stadion with the Tampere Philharmonic Orchestra, a feature-length documentary film Eput and retrospective publications.[3][1][7]
For his work as a lyricist, Syrjä has received the Juha Vainio Award award in 1997 and the Reino Helismaa Award in 2004.[1][6]
Syrjä's texts are characterised by narrative depictions of Finnish everyday life, often combining humour, irony, and introspection. He has cited Finnish songwriters Juice Leskinen, Hector and Dave Lindholm as important influences on his approach to Finnish-language rock lyrics.[6][1] Among the best-known songs for which he has written the lyrics are Murheellisten laulujen maa (1982), Tahroja paperilla (1990), Baarikärpänen (1988), Joka päivä ja joka ikinen yö (1986) and Nyt reppuni jupiset riimisi rupiset (1984).[6][1]
