after a long absence, I return with a totally random guess
Rage Against the Machine - Evil Empire
this guess has been built on very weak foundations, and specifically around the presence, on the album above of the song "Bulls on Parade" .
hints include a Bull twice (sitting Bull and the Wall street Bull) --> Bulls
Tom Morello mentioned to be inspired by the Gheto Boys sound. The Gheto boys had Big Mike as a vocalist for a short period --> Big Black was in the hints
The song refers to the building of a wall between US and Mexico --> the hints have the famous Bull of Wall Street
and with this I retire back to obscurity until the next solar eclipse
