In what could be his last solo concert for a while, Slash paid tribute to his recently departed friend Lemmy Kilmister. You can watch his performance of Motorhead's "Ace of Spades" above.

The occasion was a New Year's Eve show with Myles Kennedy & the Conspirators at the House of Blues in Las Vegas. And while the Tour section of his website says "No upcoming dates," it is widely expected that, next week, there will be an official announcement regarding about him reuniting with Axl Rose for a new tour with Guns N' Roses. Earlier this week, anonymous sources said that they are going to headline the Coachella Festival in Indio, Calif., over two weekends in April and will embark on a 25-city North American stadium tour. Coachella will reveal its lineup on Jan. 5.

For his part, Rose has been somewhat coy about the reunion. Shortly after midnight on Jan. 1, he tweeted out a New Year's greeting that "confirmed" his love of Taco Bell. And there are also the teasers featuring crowd shots over the sounds of "Welcome to the Jungle" that have been seen at pre-show reels in movie theaters across the nation. Rose will make a guest shot on ABC's Jimmy Kimmel Live! at some point next week -- rumored to be Jan. 6 -- to discuss the possibility of a reunion.

Lemmy died on Dec. 28 at the age of 70 from an aggressive form of cancer that he had only learned about two days prior. His death brought out wide assortment of metal and punk rockers expressing their love for the Motorhead frontman. Metallica, who covered Motorhead frequently, called him "Our hero," while Dave Grohl went out and got an ace of spades tattooed on his forearm. One of Lemmy's last interviews found him spectulating on the notion that his ghost could haunt other band's gigs, preferably Tears for Fears.
