Big fan of Chris Cornell. Also like Maynard from Tool, A Perfect Circle, etc. Phil Anselmo is really good
Did SAR say Chris Martin yet?
Of course McCartney/Lennon, but I never could say one stood out while on stage so I didn't put them in. I'll throw out a couple more not mentioned.
-Geddy Lee, just love the voice and obviously Rush is an acquired taste but easily one of my top 5 favorite bands
-Anthony Kiedis, great voice for one of the best of the 90's bands and still kicking a$$ today
-Sting, when he was with The Police
-Roger Daltrey, don't think I saw his name somehow
-Meatloaf, now I only am a fan of BOOH 1, but such heart he put into singing
Waters/Gilmour (hard to pick one over the other, like the Lennon/McCartney debate)
Maybe not A-list front men but need honorable mention
Ronnie Van Zant
The title was ... Best front men ... Not best music ;)
DLR ... Circa 1981
.... Then all the others ....
Etc etc etc
.... Add the Lone Rangers ... Who were not technically front men
jon bon jovi
not necessarily in that oreder.
