Dekleyn are an Electro Indie-Pop Duo hailing from Sydney’s west. Members Justin Kleyn and Matthew DeCelis began creating music together in early 2017, having known each other since 2014, when they worked on their first project under another alias.

Since 2017 the duo have released their debut album, 3 EP’s as well as a seperate single and multiple acoustic versions to add to their bodies of work.

Combining smooth vocals with heavy-hitting choruses, electronic elements and synths with guitar leads and melodies, the pair have strived to broaden the horizons of conventional indie pop.


Dekleyn have amassed a strong following online since the release of their Debut EP “Drive”, released in December 2017.

The recent success of the duo has resulted in a significant number of streams on services such as spotify, on which they have accumulated over 10 million streams in just over 3 years of releasing music.

The duo has recently expanded to a trio for their live set, including a live drummer that adds an extra dimension to their ever-evolving set.

2021 is set to be a huge year for the boys off the back of releasing their debut album “Dekleyn”.
