I don't mean instrumental only stuff (though feel free to name anything of that nature), but rather just any song and/or album which has the best guitaring you've heard.
My song pick is...
Two of the finest in Eric Clapton and Duane Allman going absolutely nuts over a classic blues rhythm...What more could you ask for?
And my album award goes to the very album that this song was taken from.
Derek and the Dominoes-Layla and Other Assorted Love Songs
Absolutely brilliant. I only wish they'd recorded more albums together.
