Since I haven't done one in awhile I thought I'd do a band that all metalheads should adore, but isn't really metal. 
Black Flag started off making the usual SoCal punk, until lead singer Henry Rollins joined the band anyway. They soon started to slide towads a more Black Sabbath influenced sludge, with the attitude of a punk band, and guitarist Greg Ginn's fascination with free jazz, which resulted in lots of atonal freak style guitar solos. This all came together on the album Family Man, where punk is all but abandoned except in attitude. Side one features nothing but Rollins doing some immature yet somehow engrossing spoken word pieces. Side two features the rest of the band doing all instrumentals which are semi-improvised pieces, with shrieking guitar solos.
