I saw Yngwie Malmsteen open for AC/DC in 85 at the Omni. I saw him open for Maiden again at the Omni in 87. People had WAY less patience for his Hendrix type guitar tricks and feedbacks that rattled the building. That's the only time I ever saw an act get booed off stage.
Best show (Of Course) was Motorhead in Charlotte back in 2011. I only regret that I didn't get to see them at a bigger venue before Lemmy died.
Saw MOTORHEAD at The Fillmore in Charlotte as well (up close and personal) and I thought that was an excellent place to witness their BADASSNESS! Long live Lemmy!
After Lemmy's death, got to see Mikkey Dee again playing drums for the Scorpions! The guy is a madman on drums!
