Sergej ?etkovi? was born in Podgorica (then known as Titograd), Montenegro, Yugoslavia on March 8, 1976.
He made his first contact with music when he was only seven years old. His first appearance was as a member of the youngest Montenegrin group at that time called "Vatrena srca" (Passionate hearts). He played piano and sang vocals. It was then when he felt the need to become a part of the professional musical life. He started his career as a singer in 1998 at the well known festival called "Suncane skale" with the song "Bila si ruza" (You were a rose). Two years after his solo debut, he published his first CD called "Kristina" in December, 2000. The CD was big success and young publishing company Goraton bought the copyrights from Pogorica's Hi-Fi centre and reprinted the CD with new label and started to sell it in all territories of former Yugoslavia . Exactly two years after his first CD, he published his second CD called "Budi mi voda" (Be my water) in December, 2002 with 12 new songs with the company Goraton. In 2003 he participated at Budva's festival (Budvanski festival) with the song "Postojim i ja" which won the best arrangement award. In 2005, Goraton published his "The Best Of" compilation. After this, Sergej presented to the media his third CD called "Kad ti zatreba" with 10 new songs. The most popular song from this last album is called "Pogledi u tami". In year 2007, he had an extremely successful tour throughout Serbia and Montenegro, which was completely sold out, and for every town, additional evenings had to be scheduled. Such success was unexpected by, perhaps, everyone. The biggest hit of the tour was the song "Pogledi u tami".
