SiGa is the stage name of Edgar Oliveira, a singer, lyricist and independent songwriter from Vale de Cambra. He has found a form of expression through writing and music, crafting a sound characterised by melancholy, nostalgia and influences from grunge, emo-rock, alternative rock and indie. On stage, he is joined by sonar, a project by Ivo Paiva, a musician and music producer whose career began on the guitar; he stands out for his exploration of different sounds, whilst always maintaining a highly personal approach to musical creation. The two artists recently released a collaborative EP.
