One of his recent exhibitions is named “The FI of The Underworld” and it follows the story of metaphysical fish swimming through physical objects. It's all based on a mushroom trip, a hallucination. He installed the Mega Mushroom, a 7 meter high sculpture at the Urban Spree Gallery in
Berlin. A second Mega Mushroom was installed on 24 May 2016 at the Red Gallery in
Shoreditch,
London. In addition to mushrooms featuring as part of a broader narrative, he is working on a fantasy book exploring the subjects of perception, consciousness and dream content. He has also expressed an ambition to build Mushroom Land, a proposed theme park that would provide a setting for his story and its characters. Aside from street art, Nagel is also a skilled musician, guitarist, composer and singer. He has designed his own guitar, "The Nail" which was built by German guitar builder, Jozsi Lak. ==Collaborations==
