Mavka is a Ukrainian band combining ethnic and folk themes with downtempo, electronica and ambient music.

The band was formed in 2013 by a theater actress Iryna Lazer (lead-singer, composer, performer) and Oleksiy Mikriukov (composer) under the initial name Crossworlds.

Since then Iryna Lazer began performing live using loop-station, vocal pedals and synthesizers creating polyphonic compositions in Ukrainian and her own invented 'Mermaid' language. In 2015 another musician joined the band due to the growing amount of live performances and the band's name was changed to Mavka.

Together they gave the concert 'Horovod under the stars' on May 27 on the stage of Kyiv Planetarium.

On December 25, 2018, the band presented an exclusive Christmas concert "Carols with the looper" in the cultural center Master Class. The main idea of the concert was for the vocalist to create and perform live the polyphonic carols by herself using only the loop-station.
