Not sure of your definition of "aggressive", but I nominate Johnny Winter Live in NYC 97'
Aggressive, live, electric blues.....
After the recent Zep live 3 disc set, Hendrix at Berkeley 2nd show, and Allman Brothers Fillmore sacd...at other legendary live shows with stellar sound that come to mind...waiting for the remaster of Hendrix's Live at winterland...SRV live maybe?
