Answer
Angelo Badalamenti and Julee Cruise collaborated multiple times. Cruise performed several songs on Badalamenti's soundtracks for David Lynch's films, most notably "Mysteries of Love" from Blue Velvet and "The World Spins" from Twin Peaks: Fire Walk with Me. Cruise also sang the title track to Badalamenti's 1986 album, Blue, and the two recorded a duet album together, Floating into the Night, in 1989.
