Ronnie James Dio was lost to cancer 4 years ago but without a doubt, his legacy will live forever. Known for some of the greatest head banging tunes in rock history, his influence is undeniable. Earlier this month, the tribute album 'This Is Your Life' hit stores with a who's who of rockers covering some of Dio's legendary work with Rainbow, Black Sabbath and his own namesake band. One contribution was a cover of 'Rainbow in the Dark' featuring Corey Taylor and Steel Panther guitarist Satchel. This tune rocks, for sure.
