Glassglue are a British experimental pop group, formed in London in 2003, by German singer, Marcel Stoetzler, and British multi-instrumentalist, Matthew Karas. After writing and arranging some material and performing as a duo, they recruited Andrea Ughetto to play bass and Ravi Low-Beer to play drums. Andrea, who was involved as a favour to Marcel, was replaced by Gianluca Galetti in 2004. Ravi Low-Beer was replaced by Emyr Tomos in 2005, but returned to the group in 2009. Matthew Karas also plays bass guitar and harmonica with The Fallen Leaves, and was a founding member of Soil.
