Delerium, a collaborative project by Bill Leeb and Rhys Fulber of Front Line Assembly, has been a pioneering force in Vancouver's music scene, blending unique sounds that fuse electronics with post-industrial vibes. Leeb's role encompasses sample selection, lyric writing, bassline creation, sequencing, and project oversight, while Fulber contributes through sampling, programming, and adding melodies and arrangements with a chords/string pad, resulting in a dance-worthy sonic mix.

After gaining recognition in cyberpunk/industrial bands like Skinny Puppy, Leeb shifted towards a more ambient dance direction with Delerium. Their breakthrough came with the 1997 album Karma, which achieved substantial commercial success, notably with the club hit "Silence" reaching high chart positions worldwide. The duo has continued their musical journey, releasing subsequent Delerium albums, with their latest offering being "Signs" in 2023.
