Sol-Angel and the Hadley St. Dreams is the second studio album by American R B singer Solange Knowles, released August 18, 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.
