Their debut 'I onda je sve počelo' (2013) released under queer feminist label Unrecords from Vienna and sophomore album 'Jantar' (2015) released as coolaboration between Unrecords and French independent label Vox Project, made them one of the most salient guitar bands of the ex-YU region. In recent years, ŽEN have performed at many major European festivals (Europavox, Colours of Ostrava, Tallinn Music Week, INmusic, Welcome to the Village...) and clubs from the Baltic to the Balkans, the Vistula River to the Atlantic sea. In 2017 they joined Slovenian Moonlee Records and in November 2017 their third album 'Sunčani ljudi' has been released.
In 2020 they have released compilation album Blender with remixes of their songs made by various music producers, and also they made a song for the movie Nun of your business.
In May 2021, on band's 11th anniversery, they released new single Uroni u san announcing their forth studio album.
ŽEN playfully dissects gender stereotypes and connects the boundaries of audio and visual art, evoking journeys through vocal harmonization submerged in a progressive symbiosis of guitar, bass, drums and synths. If we were to try to define them by genre, the closest we would get is a complex form of indie-rock, informed by various style and genre characteristics ranging from post-rock to shoegaze, math-rock, vintage synthwave and experimental electronics.

"Onstage, the band with a subtlety that tempered the high expectations, drawing me in with songs that had a beautiful ebb and flow, with layers played of noise and melody, precision playing, and unexpected chord changes and progressions." (Kevin Cole, KEXP)

"This is a perfect modern pop post-rock, math-rock, prog-indie, synthwave – very well thought out and hypnotic to watch and listen to... Zen are a beatiful misty treasure and a real find!" (Louder Than War)

"Croatia’s Zen are three stylish girls playing stadium-sized shoegaze and drone-rock with nods to Spacemen 3, My Bloody Valentine and The Cure. Their set was watertight, melodic, heavy and accompanied by unrelenting, psychedelic visuals only adding to the mind-meld and pleasing disorientation." (Clash Magazine)

"Žen and Maarja Nuut & Hendrik Kaljujärv were not just the best things we saw at Tallinn Music Week, they are two of the most enticing acts we’ve come across this year. " (The Line of Best Fit)
