Massive Attack - MezzanineOriginally April 20, 1998 Reissued April 28, 2017 Virgin Records 2xLP If Massive Attack created trip hop on their debut Blue Lines, they perfected it with Mezzanine. Whereas the former (and sophomore effort Protection) explored more casual sounds like jazz and soul, Mezzanine opted for colder, more serious soundscapes that would come to define the genre. One of the most undeniably cool albums of all time.
