Embedded Player Jack Allsopp, who records and performs under the name Just Jack, is a moody Brit-hop artist who deftly mixes hip-hop with samples, '80s electro beat machines and a touch of funk. The result from this Camden native is danceable and literate. Just Jack lacks the bravado or swagger of other rappers. His lyrics are more sedate, sometimes pessimistic, and his voice is reserved. Meditations on break-ups, hedonism and other seedy city tales are set against a steady, thumping bass.
