V4R1 is a Taipei-born heartbeat oriented vessel for composer and sound designer Sander Saarmets. V4R1 observes and explores layers and textures in time and space. V4R1 can be simultaneously minimalistic and massive, slow and intense. Intensified electronic heartbeats guide listeners through an environment of microscopic and large-scale transformations.

His eponymous debut album was released by Grainy Records in 2017. An EP under Glitch Please is set to follow in 2025.
