[citation needed] He worked as freelance sound engineer with several German acts as the new wave-band Din A Testbild[1] before becoming associated with Kraftwerk in 1989.

[2] In addition to studio work, he replaced Wolfgang Flür in concert when Kraftwerk resumed their touring activities in 1990, and engineered the album The Mix, released in 1991.

While on tour with Kraftwerk in Australia, where the band were to be Global Gathering headliners, Fritz Hilpert fell ill and was believed to have suffered some sort of heart failure.

This forced Kraftwerk to cancel the Melbourne show on 22 November 2008, but Hilpert was cleared to fly and continue the tour the next day.

[citation needed] It is thought that Hilpert's last appearance on stage with Kraftwerk was at the Cala Mijas music festival, in Malaga, Spain, on 2 September 2022.
