Paranoid
Though most of Black Sabbath's classic material from this album ("War Pigs," "Iron Man," "Fairies Wear Boots," and the title track) can also be found on the collectionWe Sold Our Soul for Rock & Roll,Paranoidis essential for the completist. One of the best albums from one of the bands to define heavy metal, this album is chock-full of the best stuff from Sabbath's Osbourne years. (Where else will you be able to hear "Rat Salad?") The music isn't exactly complex, but it doesn't need to be; its importance lies in its evocative power, with which any teenager will be able to identify.--Genevieve Williams
