It then developed during the East German era into a live music venue where many notable German bands played regularly.  Gentrification of the surrounding area in the late 2000s led to complaints about the club's noise from residents of newly constructed apartment buildings nearby.  A court case resulted, placing restrictions on the noise levels, which the owners judged made the club financially untenable, resulting in its closure on 31 December 2010.  After efforts to reopen in another district, the club secured new premises in Prenzlauer Berg and announced in February 2013 that they planned to reopen in 2016.  Delays due to construction permits pushed these plans back to 2018. Javier Mora (born May 25, 1981 in Encarnacion de Diaz, Jalisco, Mexico) is a Mexican boxer in the Heavyweight division.
