Sweden-based British musician Matt Karmil presents his third album, ++++, following his 2014 full-length debut, – – – – (PNN 007CD/LP), and IDLE033, released on Bristol label Idle Hands in 2016. His output also includes a variety of singles for labels such as New York’s Beats In Space Records and Stockholm’s Studio Barnhus. On ++++, Karmil can be heard exploring the concepts of impossible objects, reflection, symmetry, infinite perspective, truncated and stellated polyhedra, hyperbolic geometry, tessellations, and lost love. While making the music that constitutes ++++ he interacted with mathematicians George Pólya (1887-1985), Roger Penrose, and Harold Coxeter, as well as the crystallographer Friedrich Haag, and also conducted his own research into tessellation. The result is ++++, Karmil’s most clever, strange, emotional, and fun work yet, a testament to his breadth and depth as a musician.
