He has produced work on representation structures and their diffusion in semantic space. By appropriating obsolete (aesthetically, socially, economically determined) systems, he creates artworks that give rise to new value hierarchies and whose internal order can be directly translated into dynamic narratives.

In 2013, Tetzner featured in CTM’s exhibition with Give Me A Break From All This Power (A-T, 1992) and (R-N, 2000), two objects that inquire into the symbolic order of electronic music culture at a time when it was brimming with the optimistic promise of a soon-to-arrive new era of digital music. 2018 saw the presentation of his piece If the Eyes Can’t Touch (Blurred Modernism) at Berlin’s Project Space Festival, which featured 32 screenshots of modernist architecture blurred on Google Street View for reasons to do with personal rights. 

For CTM 2019, Tetzner will present I Just Can’t Avoid the Void in Avoid, a multi-channel composition woven 1500+ feedback snippets of hardcore and punk tracks released between 1981 and 2018. The work explores the subculture's continual resistance to appropriation and commercialisation, which, still going strong after over 40 years, might suggest successful strategies and codes for the perseverance of subcultures.
