In 2010 Jay Electronica played two nights at London’s Jazz Cafe (to rave reviews). During the second show he gave his Nepalese pendant to someone in the audience, later tweeting this explanation:
The other night, I gave away my chain & medallion to a brother in the crowd in London. I had to. He was from the same place I got it from.
Several days later, when Jay played in Oxford, the same Nepalese guy gave him a khukuri knife in return.
See this NME interview for more on the pendant.
