Hydrogen Sea started out in 2012 as the brain and love child of Birsen Uçar and PJ Seaux. Since then, they've released two albums: In Dreams (2016), Automata (2019) and two EPs: Court the Dark (2014) and Symbiosis (2021). Their atmospheric pop is inspired by looking up at the stars, zooming in on nature, and trying to find their place in the midst of it.
