The tempestuous and fragile relationship between record labels and artists has existed since time immemorial, and now iconic rapper Nas is firing the latest salvo in his battle with Island Def Jam. In a recent e-mail sent to executives at the label, including chairman Antonio "L.A." Reid and President/COO Steve Bartels, the rapper bluntly admonishes Island Def Jam for not releasing 'The Lost Tapes 2,' the follow up to the rapper's 2002 B-sides collection 'The Lost Tapes,' in a timely manner and claims the label doesn't fully comprehend the relationship between Nas and his fans.
