This overview of Buddy Guy's Silvertone recordings ought to be titled "Some of the best of Buddy Guy's 90s tunes, and a few throwaways as well", or something along those lines.
The first ten songs are almost all good, but the four previously unreleased songs aren't among Guy's best work, and since almost all of the previously released material here is taken from just three albums, there is really no good reason to pick up this mediocre sampler. Go with "Damn Right I've Got The Blues" and "Slippin' In" instead, and perhaps the "Feels Like Rain" album, from which "She's Nineteen Years Old" and of course "Feels Like Rain" are taken.
Only one track comes from the forgettable "Heavy Love", which is actually a credit to the compilers, and the last one, the live "My Time After Awhile", is from "Live: The Real Deal".
If you want an overview of Buddy Guy's career prior to his 90s comeback, go for Rhino Records' excellent "The Very Best Of Buddy Guy", or check out the best of his classic Chess singles on MCA/Chess' "Buddy's Blues". This is a decent sampler, but considering that it only spans four studio albums, one of which is bland at best, it is not really that much of a necessity.
