Whitesnake is one of my favorite bands...and I think that Coverdale has one of the best voices of the genre. What's your favorite Whitesnake album? Mine has gotta be their 1987 self-titled album. Although Slide It In and Slip of the Tongue are great albums, too!
I've been into Whitesnake since about 1980 and first saw them during the Come an' Get It Tour. For me, Ready n' Willing is close to being the best, hotly contested with the Geffen remixed version of Slide It In. But they all really snake, rattle n' roll for me!
