Mariusz Łuniewski is the man behind UNDERTHESKIN - one of the most respected European post-punk projects. 

In 2016 - after a very well-received worldwide self-titled debut album band performed a lot of European concerts with such iconic bands as The Soft Moon, Drab Majesty, Cold Cave, Soviet Soviet, and Lebanon Hannover to name but a few. The band also appeared at festivals, such as Sacrosanct Festival (UK), Gotham Sounds Festival (DE), Klub Dod (SE), Wave Gotik Treffen Festival (DE), etc. 
On the 29th of April 2019, Undertheskin strikes back with their second studio album  N E G A T I V E - undoubtedly his very best and enthusiastically-received album to date! One week after its premiere N E G A T I V E became the world's best-selling post-punk album on Bandcamp and the #2 all-time best-selling post-punk album!
