Allman was definitely one of the great guitarists, particularly slide guitarist. Even Clapton thought so, which is why he wanted Allman to play with Derek & the Dominos on Clapton's Layla and Other Assorted Love Songs lp. I think that Allman may have had a bigger impact on Clapton than Hendrix did, and Clapton was blown away by Hendrix.
Yep. Wasn't a big fan of those styles but he was a beast when playing.
Think some are only naming music they listen to but for me, Setzer, Prince, Satriani etc., have to be included along with a few metal and Spanish greats. If we're honestly talking talent and not just preference.
