Quite predictably, fans have begun posting the four previously unreleased songs from Black Sabbath's new tour-only CD The End onto YouTube. Unless they've been taken down since this story was posted, you can listen to "Season of the Dead" above and "Cry All Night," "Take Me Home" and "Isolated Man" below.

The new eight-song collection, split down the middle between newly unearthed tracks from the recording sessions for 2013's 13 album and live versions of songs from that same record, is only being sold at concerts on the group's current tour, also titled The End. The new songs are exactly what you'd expect and hope for: big, lumbering monsters featuring Ozzy Osbourne's distinctive vocals and more worthy selections from Tony Iommi's seemingly endless supply of fantastic guitar riffs.

The legendary metal group (founding members Osbourne, Iommi and Geezer Butler are joined by drummer Tommy Clufetos for this tour) is two shows into what they're promising will be their final farewell., You can see video from Wednesday's opening night performance in Omaha, Neb. right here.

The End tour continues Monday night (Jan. 25) in Minneapolis, Minn. You can see all the officially confirmed dates -- currently ending Sept. 21 in Phoenix, Ariz. – on the band's website. However, according to a report from opening act Rival Sons, the trek will be extended well into 2017.
