Rolf Julius was a German sound artist whose practice explored environmental acoustics. Initially trained as a visual artist, he began incorporating music into his work in the mid-1970s, developing a distinctive approach that blurred the boundaries between sculpture and musical composition. Improvisation often played a central role in Julius’s electroacoustic works, which were often presented as site-specific sound installations in public spaces. His work foregrounded subtle, quiet sounds that invited careful listening and reshaped the sensory experience of everyday environments.
