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.
