D.R.I.'s most important album (although not their best), Crossover, is pretty fun, with classics like The Five Year Plan (One of my favorite D.R.I. songs), Tear It Down, Probation, and Hooked. Some songs aren't too great though.
From beginning to end Crossover seeps full of heavy riffs, crazy drumming, and anti-establishment lyrics. It lacks the speed of D.R.I.'s earlier works, but it keeps it where it counts. This album seamlessly blends the hardcore punk and heavy metal roots that define Crossover Thrash. Purists may call this selling out, but I call it a big mosh-a-thon and everyone and your mother is invited to get some bruises!
Albums like Crossover show just how painfully obvious it is that countless successors and imitators fail at producing effective rebellious music that's simultaneously good and competent. While it definitely works best during the shorter songs (which make up most of the album), it's an overall fun listen from start to finish which just about any music listener who isn't afraid of some enjoyable metal should be able to like to a certain extent.
