2 The Music Studio on Trufo Street. CASHMERAN/ROSE/MUSK. The Trufo Studio is a music recording studio in Paris where we worked all our albums…those of Ulona Hooman, Karima Adams, Call Box, Casual Fly and recently Billy Hell…. The studio is at the top floor (fifth floor) of an old Parisian building built in 1870…. It is just under the roof of the building so we can still see the old oak beams…the place is filled with african and oriental percussions, with a silver drum kit, and a load of electric and acoustic guitars…. we love this place to create, compose and write songs…We recorded there a lot of demos….
