is an experimental electric guitar with seven strings and three outputs. The first prototype of this instrument, created in 2008, was made for guitar player Laura-Mary Carter of Blood Red Shoes. Afterwards he also made copies for Lou Barlow and dEUS' Mauro Pawlowski. For John Schmersal of Enon he built the Twister guitar, an alternate version of the Springtime. In 2009 he finished instruments for The Dodos, Liam Finn, HEALTH, Micachu and Finn Andrews of The Veils. For The Dodos and Finn he created electric 24 string drum guitars called the Tafelberg and for Andrews an electric 17-string harp guitar called the Burner guitar. He also started to perform again after a Perpignan Festival hosted by Vincent Moon and Gaspar Claus. Meanwhile, he continued to build instruments for artists such as These Are Powers, Women and Kate Nash. For his own musical career he develops a 25-meter electric long-string instrument, often featured at his performances. Besides his output as an inventor and noise musician, he starts to focus on music education, and participatory art. At first Landman started giving musicological lectures at venues, festivals and music related educational institutes. Landman published the essay 3rd Bridge Helix - From Experimental Punk to Ancient Chinese Music & the Universal Physical Laws of Consonance in which he clarifies the relation between this prepared guitar technique and the consonant values present in non-Western scales, especially the musical scale used on the Ancient Chinese musical instrument the guqin. He published an extensive 8 chapter guide on how to prepare a guitar, that was later transformed to the book Nice Noise. His lectures and presentations with his instruments prompted a request in 2009 for a practical building workshop. This gave rise to his Home Swinger project, which allowed people to participate in DIY workshops where they could build their own copy of his newly created instrument the Home Swinger. Often this was followed by a rehearsal and ensemble performance, with multiple copies of the Home Swinger, drums, basses, and guitars, in the style of the Rhys Chatham and Glenn Branca compositions. Events took place throughout all European countries and the US. The Home Swinger was selected as one of the instruments for the second Guthman Musical Instrument Competition at Georgia Tech, Atlanta, in February 2010. Along with the Moodswinger, this instrument is included in the permanent collection of the Musical Instrument Museum in Phoenix, Arizona. Soon
