Zöldhullám is a 5 piece band, having acoustic music in their focus. Let it be a song originally performed by others, or one of their own (Csaba Mester, the lead singer being both the composer and author of their songs) they add their unique sound to it: A cajón as the backbone of the rhythm section and instruments appearing like an accordion, a banjo or a violin. The language of their performance is Hungarian and the lyrics really do make a difference with a lot of deep thoughts behind the graceful rhymes. They also emphasize vocal qualities, supporting the lead with at least 2 other vocals most of the time. A value that is very rare on the Hungarian pop scene.
