When Felix joined D.R.I. in 1984 he brought a new audience to the shows. The next three years the band toured and started developing a new genre, (along with other pioneers) crossover. Their third album, "Crossover", released in 1987, was suitingly named since the songs on this album had a strong metal sound to them. As the band began to "crossover" to thrash, their songs became longer, slower, and more complex. The press has called D.R.I. the major band of the "crossover" movement, a style that combined hardcore punk and thrash metal. This music invited a mixed audience of punks, skinheads, and metal fans to their shows.
