Unda-Vybe Studio

State 51.
From an interview with Karl "Tuff Enuff" Brown:
"Our little hub was our studio at the Alaska building over near Tower Bridge. We were on the car park level of the building and Fifty First Recordings, the record label, was on the other side."
The photo shows Karl and Todd Edwards in the studio in the late 1990s.
Listed on some releases as UV Studios / UVM Studios.
Some Tuff Jam releases were mixed and engineered at Catch Studios.
