after the start of the Home Swinger workshops his job as a teacher/artistbecame a full-time activity with an ongoing tour schedule throughout the whole year. He developed a wide of range of workshops with different kinds of instruments, and created this way thousands of DIY kalimbas, triochords, plates with crossed strings, and mallet guitars. Due to the ongoing tour schedule with the DIY-instrument projects, he discontinued the production of his high-end products for bands, although he makes exceptions such as developing a 42-stringed instrument for Peter James Taylor; nine exclusive instruments for Belgian composer Serge Verstockt; instruments for befriended acts such as Lau Nau, Tomoko Sauvage, Hifi Club, Remko Scha, Ritornel, Katharine Klement, Killed by 9V Batteries and Ex-Easter Island Head; and an instrument for the SONS Museum in 2011. Because of his touring with the workshops he connects more to the experimental music scene, performing with acts such as Jad Fair, Rhys Chatham, Wu Fei, Noël Akchoté, Action Beat, Dustin Wong (ex Ponytail), Camera,and others. In 2012, he published an album featuring Jad Fair and the French noise artist Philippe Petit. He also started a two piece band called Bismuth with multi-instrumentalist Arnold van de Velde. In the same year he started his Strat Eraser Project and built a series of instruments for direct sale, along with the workshop exclusive models. In November he gave a TEDx talk. Around this time, he began to depart from building stringed instruments. Inspired by the percussive works of Lou Harrison, John Cage, and the Belgian sound artist George Smits, and the sounds of Indonesian Gamelan instruments, he created a collection of metal percussion instruments and amplified them with guitar pickups. These instruments are widely used on the recordings of Bismuth and in his live performances. Also, he built a set of motor instruments and invented an instrument made from PET bottles. The March 2013 edition of Premier Guitar featured a cover story written by Landman about a guitar modification he did on request of the magazine. Later that year the documentary Alles, Tot Dit was published. In April 2014 Bismuth released their debut album. This album was published in a limited deluxe edition as well with a special designed instrument called 'Svikt' mounted to the album cover. In the same year he starts his solo performances and collaborates with the Dutch noise rock act Those Foreign Kids, functioning as his backing band
