Ultrasound are an English indie rock band. With roots in the British underground psychedelic and experimental rock scenes of the 1980s and early 1990s, the band emerged in 1997 and soon gained attention for their "operatic prog-glam ambitions" and "violent reworking of the idiosyncratic compositions of Captain Beefheart and the staged ambisexual pop idioms of the likes of Marc Bolan and David Bowie".
