Here's what I said about this classic on my Run DMC post a few months back (http://mayepov.blogspot.com/2012/07/run-dmc.html):
Released in 1984, this is the album that started it all and not only does it still hold up WELL after 28 years, it remains their best album and one of the greatest albums of all time. Whether it was talking about the issues at the time ("Hard Times"), biggin up their DJ ("Jam-Master Jay"), integrating hip hop and rock for the first time ("Rock Box"), they were at the top of their game, early game on this album, and it has aged quite well.
Rating- 5 stars
