Tomi "Varre" Vartiainen (b. 1974) changed piano for guitar at the age of 10 and started his guitar lessons in the Music School of Kerava where the first bands of the guitarist were also formed. After Sibelius high school Vartiainen studied a couple of years in the Pop & Jazz Conservatory of Oulunkylä and spent a year in the Hamina Military Band, until in 1997 he started his studies at the jazz department of Sibelius Academy.

In the late-1990s Vartiainen played in several bands from different music genres. In 1998 he performed at the UMO Jazz Orchestra's Young Soloists' Concert and recorded a radio tape with drummer Mikko Hassinen's band the same year. Vartiainen played also in pianist Kari Ikonen's Karikko-band and in his own Bingo-trio.

In 2000 Vartiainen formed the Husband Trio with bassist Harri Rantanen and drummer Anssi Nykänen, that became quickly a very successful grooveband in Finland. Husband fused jazz and rock music elements and performed both at jazzclubs and rockarenas. Later also guitarist Marzi Nyman, who had featured on Husband's gigs, joined the group.
