Duvel Mortgage
“The Chalcotribe”
Saturday 12th September
5 Florence Street, Glasgow, G5
From 7pm

Ambrose Cadman. Rectilinear chair of The Berrenthorpe Brass Rubbing Society. Devoted husband to Dorothea, much talked about but never seen. Revered benefactor of the most ancient of Huntingdonshire churches, St Asaph’s. A man of impeccable plumage. So why the local murmurings? The wheedling torsional frequencies seeming to emanate from the very flower beds of Cadman’s baronial pile. The grisly demise of Victor Rogers, stalwart pilot of the local omnibus. The inexplicable disappearance of schoolboy detective, Raymond Sleet. The equally inexplicable appearance of Otto Naismith, whose very name might be a clue to the peculiar goings-on.
Duvel Mortgage is the trio of Sophie Sleigh-Johnson and The Bohman Brothers. The group performs a carefully blended mix of offbeat poetics, low-lying music, and sound obstruction using unconventional instruments and household materials. As of late 2025, they have been pursuing a zig-zag course through the United Kingdom.
Writer and artist Sophie Sleigh-Johnson lives in Southend-on-Sea. Her work performatively brings popular culture into communion with magic, place and esoterica, and is distributed across audio and spoken word performance, printmaking, cassette releases and writing.
Her book Code: Damp – An Esoteric Guide to British Sitcoms (2024), published by Repeater Books, examined the sitcoms of 1970s TV actor Leonard Rossiter in relation to mystical and arcane counter histories. She is also a contributor to Darkside magazine Faunus, TON and The London Drinker.
Recent projects include her curation of a special Code:Damp Experimenta Mixtape series at the BFI Southbank. She lectures in Fine Art Critical Studies at Goldsmiths College, University of London.

The Bohman Brothers
Adam Bohman and Jonathan Bohman have been recording together since their early teens and playing live since 1984.
Their repertoire includes a combination of sounds created in the moment and distinct compositions including songs. They use unconventional instruments, household objects, dislocated text from found, literary and commercial sources and collaged layers of recordings.
Regular gigs started in the mid-90s in London at places like The Club Room in Penton Street, The Red Rose in Seven Sisters Road and The Klinker in De Beauvoir. From 2000 to 2005 they had their own concert series upstairs at The Bonnington Café in Vauxhall, London. From 2005 to present day, they have continued in the same vein – most recently Adam’s monthly event at The Royal Albert, New Cross.
Working together they are in a number of groups, including: Secluded Bronte with Richard Thomas, The BBC with Richard Crow, Ischio Romantico with Leonard Aspen & Roger Boulding, The Dave Craught Five with Romuald Wadych and now Duvel Mortgage with Sophie Sleigh-Johnson. They have also worked with film-maker Peter Strickland on various projects.
They have performed at Tate Britain, Tate Modern, Roundhouse, Royal Albert Hall, South Bank and numerous venues around the UK, Europe and America.
Their duo recordings include ‘A Twist For All Pockets’ (Rossbin, 2001), ‘Purely Practical’ (Peripheral Conserve, 2002), ‘Back On The Streets’ (Peripheral Conserve, 2012), ‘Library Music’ (Des Astres D’Or, 2019), ‘In Their 70s’ (Fort Evil Fruit, 2021), ‘Room Service ‘ (Rural Isolation Project, 2024) and ‘Xosprrorsindy’ (Burselm Crypt Recordings, 2026)
