All depends what venue;
but my fav all time singers are the following (some are rock singers some are not but they are all acknowledged as influencing music today)
David Bowie ( Alladin Sane was his best work vocally especially "Time")
Bryan Ferry of Roxy Music ( Listen to "Avalon")
Roger Daltrey ( Nothing compares to "Who's Next" aka "Lifehouse" "Behind Blue eyes")
Robert Plant ("Battle of Evermore")
K.D.Lang (Ingenue and Shadowlands "Black Coffee")
Ricky Lee Jones ( "Making Whoopee")
Loreena McKennit ( "All Souls Night")
Frank Sinatra (Anything from the 50's and 60's)
Bobby Darin ( "Mack the Knife")
Lou Rawls ("Willow weep for me")
Marvin Gaye ( "What's goin on")
Aretha Franklin ( "That's what I'm gonna do")
Warren Zevon ("Splendid Isolation")
Bob Marley ("Wait in Vain")
Bob Seger (Slim Whitman's classic "Blame it on the Moonlight")
There are many more but when I think of artists that use or have used thier voices to make musical history of great influence those are some of my favorites.
