OPO is a Rock band from Rijeka, Croatia formed in 2011.

We sound… well, a bit angry, yes! Well that’s the general idea of rock and roll isn’t it? 😉
But that anger is driven by lyrics with that inspire a positive change in us, and the music mirrors that energy.

OPO has a specific mix of heavy riffs and rhythms, coupled with direct vocal melodies and sound processing to create a unique modern, industrial and alternative rock sound.
