This festival, which was originally called Mat Mad, is back in the same place and same time of year as 2016. In the words of the organisers, 'Mat Mad has evolved and broadened. Mad Music City will still carry Matadero Madrid in its heart, and project that energy to the various spaces and places involved to make this Madrid's newest and most unique multidisciplinary festival with five days of events and activities related to music'. Last year's acts included Parov Stelar, Imelda May, Unknown Mortal Orchestra, Molotov Jukebox and Soleá Morente. This year's are still to be confirmed.
