Israeli violinist Miri Ben-Ari will perform at this Sunday's dedication of the Martin Luther King Jr Memorial in Washington DC. The US-resident Ben-Ari, who has become known for her hip-hop violin style, is the only non-African-American artist performing at the dedication ceremony, which will also feature addresses by civil rights leaders and President Barack Obama.

The memorial in West Potomac Park cost $120m and comprises a 450ft inscription wall and a 30ft-high relief of King. It was to have been dedicated on 28 August, but organisers postponed the event because of Hurricane Irene.
