New York theater workshop Badalamenti had produced. The result of their initial collaboration was "Mysteries of Love", which figures prominently in Blue Velvets closing scenes and gained a cult following. Badalamenti and Lynch went on to write and produce additional songs for Cruise, most of which were featured in her debut album, Floating into the Night (1989). The album was released on September 12, 1989 by Warner Bros. Records, and charted on Billboard the following year. It also provided musical material for Lynch's Industrial Symphony No. 1, in which Cruise performed while "floating" from a harness dozens of feet above a stage at the Brooklyn Academy of Music. The second, more significant project was the soundtrack to Lynch's Twin Peaks, for which Badalamenti composed the original score. The song "Falling", which became the orchestral theme for the television series, caused a minor sensation, winning a Grammy at the 33rd Annual Grammy Awards in 1991 for Best Pop Instrumental. The Twin Peaks soundtrack, featuring Cruise on the songs "Into the Night" and "The Nightingale" as well as on the vocal version of "Falling", eventually went gold (500,000+ copies) in the U.S., a rare feat for a television soundtrack. Cruise made a number of appearances on Twin Peaks as a singer at a local bar, and was prominently featured in both the show's landmark pilot episode and the episode where Laura Palmer's murderer is revealed, as well as in 1992's Twin Peaks: Fire Walk with Me. "Rockin' Back Inside My Heart", the second single from Floating into the Night, was released in 1990 and was also featured in an episode of Twin Peaks along with "The World Spins"; in the episode, several of the main female characters are shown lip-synching to "Rockin' Back Inside My Heart". Cruise reinterpreted and sang the theme song for an episode of the USA Network show Psych. The episode, "Dual Spires", was about a secluded town full of secrets and skeletons while they investigate the murder of a girl. It aired 20 years to the day after Laura Palmer's murderer was revealed. Cruise appeared on Saturday Night Live on May 12, 1990, filling in along with Spanic Boys on short notice when scheduled performer Sinéad O'Connor refused to appear on the same show as guest host Andrew Dice Clay. Cruise performed "Falling". The following year, Cruise recorded a Lynch- and Badalamenti-produced cover of the Elvis Presley song
