Opus Pro are a latvian hard rock band, that originated from two other bands Opus and Metronoms back in 1986. They are one of the most respected Latvian rock acts, although their lyrical themes are often cited as being "too bubble gum and cheesy". The band is famous for their patriotic anthem Brivibu Baltijai and their slow-tempo love ballads Roza Lietus and Sonakt. Recently they have teamed up with young singer Aisha for a new album, which is due to come out in 2007.
