He left the band in 1992 due to the birth of his first child, and joined Swans' bandleader Michael Gira's follow-up project Angels of Light.

His approach to the lap-steel guitar is non-traditional, often devoted to playing drones that can serve as either supporting background elements or take a more prominent role in the band's music.

[1] In the late 1990s he rejoined forces with long time friend and collaborator Thomas Wydler (Nick Cave and the Bad Seeds) who had already played drums on his 1988 EP Down by Love, and together with singer Viola Limpet they formed the rock'n'roll-noir ensemble Les Hommes Sauvages.

[10] Besides his band activities Hahn has recorded movie soundtracks for German director Robert Schwentke (Eierdiebe/The Family Jewels - 2003) and Austrian film-maker Marko Doringer (Mein Halbes Leben – 2008, Naegel mit Köpfen – 2013).

[12] Additional translated works include The Song of the Silent Snow by Hubert Selby Jr., Margrave of the Marshes, by John Peel, and Thy Neighbor's Wife by Gay Talese[2]
