Rammstein recently performed a new song, or at least a part of a new song with a introductory piece tied into it, titled "Ramm 4" live for the first time ever. It's a song presumably off the band's upcoming record, whatever stage that may be in currently, and it's a got a pretty heavy swing to it.
The band performed at Hellfest in France, and naturally opened up with "Ramm 4," though this time the sound quality is much better!
