Bio/Disko

Cologne-based multi-instrumentalist David Helm and singer-songwriter Marek Johnson began his musical career with the Limburg Cathedral Boys‘ Choir. In contrast, during this time he devoted himself to the sound of noisy bands at muddy small-town punk rock festivals. In 2015, he completed his double bass studies at the HfMT Cologne.
As a highly acclaimed double bassist and improviser, he received the Cologne Jazz Prize in 2019. David can be heard on over 80 recordings and performs worldwide with numerous bands in a wide variety of musical contexts such as the German/Danish collective Fosterchild, the Shannon Barnett Quartet, Pollon and Own Your Bones. He currently performs as a harpsichordist and pianist in Emily Wittbrodt’s song cycle ‘Wearing Words’.
 
His own projects include a free improvisating duo with Parisian pianist Jozef Dumoulin, in which David Helm devotes himself to sound art with voice, guitar, objects and electronics. The debut album ‘No-Eyed Deer’ was released in 2022 on the Berlin label Anunaki Tabla. 
In the summer of 2025, he released the debut album ‘First Crash’ by the electro-noise band Placebo Domingo together with Philip Zoubek and Dominik Mahnig. 
At the end of the year, the third Marek Johnson album ‘Limbs’ will be released on Papercup Records.
