Of course it's subjective. I saw Pete Morton do a smashing gig last night. One day I'll hear Paul Downes or Martin Carthy close up again and be thrilled. Bert Jansch is never long off my CD player and there are many Mudcatters who regularly get played too. What does "good voice" mean? I love the reedy sound of Mississippi John Hurt and the roar of Leadbelly. There is the smooth grace of Belafonte and the growl of Muddy Waters. I love em all. I don't believe in "good voices". Bad singers can make "good voices" dull. Good singers make songs come alive. They make their voices sound right.
