David Maranha (PT) and Patrícia Machás (PT) are both architects and musicians working and living in Lisbon. Along with their work in architecture, they are both part of the current formation of “Osso Exótico”. Maranha started to develop his work as a musician in the mid-1980s. In 1989 he created the experimental group “Osso Exótico” along with André Maranha, Bernardo Devlin and António Forte. With a regular and extensive live and recorded activity in Portugal and abroad, the ensemble utilizes a range of mainly acoustic, often modified, instruments. With glass harmonica, piano strings, percussion or violin the ensemble created drone and at times mystical as well as psychedelic ambiences. In addition, the duo works as architects creating public buildings as museums, schools, senior residences and cemeteries.
