"The world is a test for us. The world is stress and sin..." – sings the frontman of Ostava band, Svilen Noev, in the song "Test" which explores the changed world and its subjugated love. Recently, the musicians presented the video to the latest single from their album "Oxygen". The song intertwines punk and pop sounds – a mix that everyone in the band values greatly. The music and lyrics of the song were written by the band‘s guitarist Georgi Georgiev, who explains that all members of Ostava contributed to the arrangement of "Test".

''The song is actually about the test within a relationship, about the questions, decisions, compromises and boundaries with those things. It's about the finds between people, the stages they go through, and especially the issue of forgiveness as a purgatory of accumulated negative emotions. Love as a test", says Georgi Georgiev.
