Query: Black Sabbath - self-titled (Warner Bros.)

Review number 227.Originally unleashed upon an unexpected world of young hard rock listeners in 1970.Was,of course the band's chilling debut record.Many say that this lp was one of THE most influential heavy rock albums of all time.I believe it.I remember hearing about HOW Sabbath's very first tour literally shook the walls of mid-sized concert venues.Your CD player will register this disc as having five tracks,but there seems to be ten actual songs,many of them run together.From the stunning opener(complete with church bells-a-ringing)the band's namesake "Black Sabbath" to "Behind The Wall Of Sleep",the blues-like "The Wizard" and "Sleeping Village",one gets to fully experience vintage doom metal here.I mean,those current stoner/doom bands you hear of today are nice,but THIS is the real thing.Most highly recommended.
