I think Joe will be playing with the Less Is More guideline in Black Country, & he's stated in interviews that the emphasis is on ROCK not Blues in this band.
I'm sure Hughes will bring some Funk into the mix, but hopefully not too much.
Jason deserves to be in a band of his own again since he's filled in for other drummers for so long, playing in UFO, Foreigner, & his dad's band.
I really LOVED his band BONHAM & got to be Front Row Center with one of my hottest girlfriends ever for one of their shows.
Derek Sherinian has proved himself by playing in DreamTheater & Planet X but he'll be glad I'm sure too if this band is successful enuf to stay together for a good long while.
They certainly are a Supergroup & I'm sure they'll give us at least one great album like Blind Faith did, but I'm hopin' they'll keep on Rockin' together after that & produce several albums of great songs & music!!
