Sol-Angel and The Hadley St. Dreams

Sol-Angel and the Hadley St. Dreams is the second studio album by American R&B singer Solange Knowles, released August 26, 2008, on Polydor Records and Music World. Recording during 2005 to 2008, Knowles was heavily influenced by the "Motown Sound" of the 1960s and 1970s during the album's conception, prompting her to work with several vintage-style producers and songwriters such as Cee-Lo Green, Mark Ronson, and former Holland–Dozier–Holland composer Lamont Dozier. Exploring the lyrical theme of independence, it also incorporates elements of downbeat and electronic music that she had familiarized herself with on previous trips to Europe.

Deviating from the R&B and dance-pop of Knowles' debut album, Solo Star (2002), Sol-Angel and the Hadley St. Dreams featured promotion that aimed at an "intellectual, backpacking, coffee shop, digital kid" audience. The album debuted at number nine on the US Billboard 200 chart, selling 46,000 copies in its first week, and spawned three singles that attained chart success as number-one Billboard Dance hits. Upon its release, Sol-Angel and the Hadley St. Dreams received generally positive reviews from most music critics. As of April 2009, it has sold 138,000 copies in the United States.
