A variety of moods, instrumental foundations, post-rock and electronic elements, all combined with an intense visual experience – this is how Deley started in 2012 and the direction hasn’t changed since. In 2013, they debuted with the EP Adventures in Psychoacoustics, which was included on three post-rock compilation albums. In autumn 2016, the new album Sounds of Science finally arrived, and the guys developed a completely new visual with the help of János Molnár Trippy. In the meantime, Sounds of Science has toured the Hungarian SUN and Börzsönystock festivals, as well as the Valley of Arts, and has been presented abroad at the Dutch Uncloud and Romanian Cobra festivals.
Following the 2016 album, the band has released a live album entitled Clutch!, which is the soundtrack of a concert at the legendary Kuplung club in Budapest. Over the years, the band has also played in many clubs in Hungary and, in addition to their own nights, have supported bands such as Public Service Broadcasting (UK), Tides From Nebula (PL), Sleepmakeswaves (AU) and Our Ceasing Voice (AT). After the releases of Adventures in Psychoacoustics (2013) , Sounds of Science (2016) and Clutch (2018), the album „Choose your reality” arrived at the end of 2023, which the band, who have undergone updates in the meantime, presented with renewed vigour at the cult Tandem bar at the top of the Danube Bend.
