(AllHipHop News) A highly anticipated concert featuring Nas and Damian Marley in the United Kingdom has been cancelled, due to a massive ash cloud that formed as a result of a volcanic eruption in Iceland. Nas and Damian Marley were slated to perform at The Electric Ballroom in London this Wednesday (April 21st). The event has been scrapped due to the eruption of a volcano beneath the Eyjafjallajokull glacier in southern Iceland.The volcano began erupting on March 20th, after being dormant for over 200 years. According to witnesses, the volcano spit fire streams as high as 100 meters. Thousands of flights have since been cancelled and over 23 countries in Europe have been affected by the eruption. Ushers tour plans have also been impacted. The singer was slated to launch a promotional tour in the UK this week to support his #1 track OMG, but that also has been cancelled.
