Black Sabbath are currently touring down under, and they're taking every opportunity to work in new material into their sets. The latest song to make its debut is the track 'Loner,' which does appear on the upcoming '13' album.

Fan-shot footage of the group performing the track in Melbourne last night (May 1) can be seen below. The song finds guitarist Tony Iommi hitting the mark with a repetitive foot-stomping guitar groove and touring drummer Tommy Clufetos nimbly rocking his way behind the kit to the original licks laid down by Rage Against the Machine's Brad Wilk in the studio.

For those keeping count, 'Loner' follows 'God Is Dead?,' 'End of the Beginning' and the '13' album bonus cut, 'Methademic,' which have all debuted live on the band's current trek.

In other Black Sabbath touring news, the band has added a South American leg to their 2013 World Tour. Stops on the run include appearances in Chile and Brazil. The newly added stops can be seen below.
