sorry i couldn't help you with any new rawk.
I got to say I find Plant’s solo career underwhelming...even that album with Alison Krauss is soooooo boring
agreed. i'm arguably the biggest Zep fan here, and his solo stuff leaves me cold. a decent track here and there, but low signal-to-noise ratio.
fact nobody cares about: my first arena/stadium concert was robert plant (openers: the black crows) in 1988 if i remember correctly.
