VH1 Classic's 'That Metal Show' will return to the airwaves Jan. 18 for its 13th season, with hosts Eddie Trunk, Don Jamieson and Jim Florentine bringing viewers the best in metal guests. There have been plenty of legendary guests over the years, but still there are some iconic musicians who have yet to appear on the show. This poll asks which metal performer who hasn't yet appeared on 'That Metal Show' you would most like to see on the program.

Though Kerry King and Dave Lombardo have represented Slayer in the past, the band's frontman Tom Araya would be an excellent guest on 'That Metal Show.' With a new album in the works, the timing would be great for an Araya appearance. Likewise, Steve Harris and Adrian Smith from Iron Maiden have dropped by, but an appearance from singer Bruce Dickinson would be more than welcome. And how about a visit from a modern legend like Tool frontman Maynard James Keenan as the band ramps up to a new and highly anticipated album?

While Black Sabbath's Bill Ward, Geezer Butler and Tony Iommi have all graced the 'That Metal Show' set, Ozzy Osbourne remains a holdout. And while Vince Neil has been a guest in the past, an appearance from Motley Crue's most vocal member, bassist Nikki Sixx, as the band prepares for their farewell tour would be a great "get."

So those are your choices. Now let us know which of these rockers you'd most like to see appear on VH1 Classic's 'That Metal Show' by voting in the poll below. And remember to tune in Jan. 18 for the Season 13 premiere of 'That Metal Show' on VH1 Classic. You can also keep up with the show via the official 'That Metal Show' website and Facebook page.
