Now I'm not a huge fan of tribute albums most are rushed to be put together and are usually not that good.   I came across an article about a new tribute album for Ronnie James Dio and seeing the names involved it looks like it maybe one worth checking out. Metallica, Rob Halford, Motorhead, Scorpions, among many that will be apart of this, and funds from the sales of the album will benefit Ronnie's  "Stand Up and Shout Cancer Fund".  You can read more details on the album and track listing here.
