Excuse me, but i think that vocals over ANY other instrument are a matter of taste...as everybody sounds so very much different. You cant have best singers and worst singers...its opinion.
Labrie is the main reason i listen to DT, and i think he has a truely unique and incredible voice.
Maybe not. Im not hes big fan, but do you mean about Alpines keyboard playing? Im listening more Richard Andersson, Pinella, Kevin Codfert, Jordan Rudess you know probably.
