Masstishaddhu has been played on NTS shows including Elena Colombi, with Angels Gather Here Between Purity Of Heart And Hopeless Despair first played on 18 June 2018.

Masstishaddhu was a British trio comprising musicians from Metgumbnerbone, Sean Breadin (aka B. Sedayne), Matt Watson and Richard Rupenus (also of The New Blockaders). The trio released their only album, Shekinah, in 1988 on Steven Stapleton's United Dairies label. The members of Masstishaddhu eventually went on to make more music, Richard Rupenaus as a member of Nihilist Assault Group (among others). and Sean Breadin often recording under the name Sedayne ,

Masstishaddhu's album, Shekinah, was released in a limited quantity and, for the most part, it was overlooked and fell into an abyss of collector-talk and rumors. Thanks to the reintroduction by the new label Psychedelic Pig, and the remastering job by Colin Potter, Masstishaddhu's Shekinah was re-issued. The word "shekinah" is Hebrew and translates roughly as "the presence of God" or as that light which is visible in the presence of God (as God appeared to Moses and others, for example). The title is highly appropriate as the two twenty-plus minute tracks often shine in an inexplicable way. The music burns slowly and washes the space it occupies with sweet and smokey incense, but the interplay of the voices and instruments emanates a bright and insistent energy that escapes the world of words and can only be described, with caution, as a feeling or a presence.
