A never before released Lauryn Hill track hit the 'net Sunday and could be the fruits of a much anticipated comeback or a leftover track from previous studio sessions. Either way, it's always great to hear from the reclusive singer/rapper. In other Hill news, the singer will join Snoop Dogg, A Tribe Called Quest, the Wu-Tang Clan, Rakim, KRS-One, Slick Rick, Murs, 9th Wonder and many more, when she takes the stage at this year's Rock the Bells traveling festival, which kicks off August 21 in Los Angeles.
