No...first of all, it's how his voice is...it's just his, and by being nearly identical to Plant, there will always be a putdown of being copycats, but it's just his voice.... 2nd they really are FINALLY a throwback 70's hard rock band at its best...and they are awesome...if you're going to do classic rock you'll inadvertently have parallels to some band out there, and being close to Zep is probably the best one can do. Finally on their 2 CD's they do evolve into their own sound somewhat, and again, it's awesome !!!!!!!!!!!!!!!
And keep in mind that they are just around +- 20 years of age. Man, the future of rock music looks bright, and I for one hope that because of GVF there will be other bands to follow.........
