**Nina Ryser** was born and raised in Brooklyn, NY, and has been based in Philadelphia, PA since 2015. She has played in many bands over the years, including **Palberta, @, Shimmer, Data, Fire Roast, Kristine Leschper** and **Lily Konigsberg**, among several others. Nina's solo experimental synth-pop project has taken on many forms over the years, but at its core are lush synth compositions, drum machine, various electronics, and pop-leaning vocal melodies.
**taupe** is a three-piece live band, veering from taut metronomic precision into intentionally turbulent, unchartered territory. A DIY ethos feeds their wonky compositions, colliding sour scatter-skronk with sludgy, doom-inspired riffs that has won them support from the likes of BBC 6 Music’s **Freak Zone** and BBC Radio 3’s **Late Junction** and **Freeness**. Taupe are a non-jazz band that prizes surprise over any specific sound.
**Jason Kolàr**, also known as **Cristian Subirà**, is a pivotal artist in Barcelona’s contemporary underground scene. His musical creations are acclaimed for their immersive and emotional qualities, earning recognition from labels such as **Stroom, Students of Decay, Dauw,** and **Aguirre Records**. Subirà's sonic explorations move through uncharted realms of sound in pursuit of a vibrant listening experience.
**Rio Vaupes/Uapes** bring you homemade sound experiments, carried out by **Juan Felipe Gallo** and **Kauê Werner**. Through the use of synthesizers, guitars, bass, drum machines and samplers, several experimentation sessions resulted in a soundtrack of an adventurous history of two friends that decided to explore the Amazonian area around the border between Colombia and Brazil.
*This event is made possible with the kind support of Popunie Rotterdam, Stichting Volkskracht, Fonds Podiumkunsten, Gemeente Rotterdam and Stimuleringsfonds Creatieve Industrie.*
