Subsequent Erstwhile releases have largely focused on slow-moving, often quiet compositions played using non-standard computers and electronics (such as Sachiko M's "empty sampler" or Toshimaru Nakamura's "no-input mixing board"). These electronics often get paired with acoustic instruments, which are then played with amplification and extended techniques. The most prominent example of this modified instrumentation is Keith Rowe's tabletop guitar, which he uses to create textured soundscapes by incorporating household objects and sampled radio transmissions through the instrument's pickups. Another instance includes trumpeters Matt Davis and Axel Dörner, who sometimes play their instruments by blowing through the valves rather than the mouthpiece.
