As part of Amazon’s monthly $5 MP3 Album Deals, Massive Attack‘s 1991 debut album Blue Lines is currently on sale for only $5. You can check out a track listing here below.

Blue Lines is widely considered to be the first trip-hop album. At the time of its release electronic music was associated with upbeat dance tracks, but Massive Attack sought to evolve their own sound by fusing down-tempo hip hop, soul, reggae, and other musical and lyrical influences important to the group’s history. What resulted from their painstaking efforts became a hallmark for British electronic music production and gave rise to “chill out” electronica.
