Trained at the Academy of Music in Vienna, Austria, Haslinger graduated straight into active work in the European music business, first recording with Hypersax, culminating in his joining Tangerine Dream in time for the recording of Underwater Sunlight (1986). He brought a certain amount of structure to the band's compositions, resulting in some of the more improvisational elements being jettisoned; the change in direction shaped the progress of the group into the '90s. Haslinger remained with Tangerine Dream until the end of 1990, pursuing graduate studies in music between recording dates and live tours, appearing on more than 14 albums, regular and soundtrack, before his departure (a 15th album, the soundtrack to The Park Is Mine, appeared in 1992).
In 1991, Haslinger began a collaboration with Lightwave, a French experimental group. He relocated to Los Angeles at the same time, eventually creating a studio that he dubbed "The Assembly Room." His pace of work has never slackened -- several albums with Lightwave, the release of 1994's Future Primitive (under his surname only), and 1996's World Without Rules are only the tip of the iceberg. Haslinger has provided music for everything from interactive CD-Rs (such as his 1997 soundtrack to the animated short film Planetary Traveler) to convention openings. He has also developed his own unique musical processes to help drive his creativity and lead him in interesting musical directions, with the Coma Virus album Hidden (1996) displaying some of the results of these "Assembly strategies."
Haslinger began scoring short films in the late '90s, in addition to programming and arranging film scores by Graeme Revell, including The Siege, Pitch Black, and Lara Croft: Tomb Raider. Starting with the 2000 HBO film Cheaters, Haslinger scored several films by director John Stockwell, including Crazy/Beautiful and Blue Crush. He began scoring video games with 2005's Far Cry Instincts for Ubisoft Entertainment. Haslinger's music for the Showtime series Sleeper Cell was nominated for an Emmy Award in 2007. Other notable soundtracks Haslinger has composed include Death Race (2008), Underworld: Rise of the Lycans (2009), The Three Musketeers (2011), Underworld: Awakening (2012), Resident Evil: The Final Chapter (2016), and the AMC series Halt and Catch Fire and Fear the Walking Dead.
In 2019, Haslinger and Peter Baumann (another Tangerine Dream alumnus) collaborated for the first time since their unreleased Blue Room project dating back to the early '90s and issued a self-titled album under the name Neuland. Haslinger released a neo-classical solo album titled Exit Ghost in 2020, which he followed with the similar Exit Ghost II in 2021. ~ Steven McDonald & Paul Simpson, Rovi
