Curtis Williams, the leading personality in Atlanta's buzzing Two-9 collective, drops his second solo mixtape, 'Half Forgotten Daydreams.'

Running 15 tracks, the project deviates from pretty much anything out of Atlanta in the last decade. You won't hear much influence from kingpins like T.I., Young Jeezy or Gucci Mane -- you can trace the breadcrumbs back to West Coast spitters like Kurupt and Nipsey Hussle, if anyone -- but there is plenty to enjoy by way of sharp rhymes and smooth, blunted beats.

When Curtis does attempt a typical Atlanta anthem, he does it well. Cuts like 'Automatic' and 'Bare Essentials' exhibit his ability to slow down the flow, up the braggadocio and drop a catchy hook while he's at it.

Much like how the Two-9 crew has looked to build their own "cool" as opposed to chasing everybody else's, Curtis keeps things largely in-house on 'Half Forgotten Daydreams.' Childish Major (the guy behind Rocko's 'U.O.E.N.O.') picks up the most production credits, while fellow up-and-comers and close friends Robb Bank$ and Vic Mensa register on the guestlist.
