Tom Morello

But will it ever see an official release?

The guitarist talks at Sonic Temple.

That should count as more than one signature, right?

The Prophet of Rage hits the road in support of his recent solo vehicle.

The guitarist says there's not a lot of music, but there is some and that it will be released at some point.

'One thing I will not be doing is shutting up any time soon,' Morello says.

As always, Morello melts faces, but he never gets in the way of songs featuring Marcus Mumford, K. Flay and Outkast's Big Boi.

The song features Portugal. The Man’s John Gourley and Whethan and honors the late Chris Cornell by tackling the stigma surrounding mental health.
