Mine are all old-school (Old's Kool) from my grade school days through my teens. These are the bands that far and away I played the most and or had the most influence. Difficult to narrow it down to four. This is chronological for me.
Edit... I really need to get Motley Crue in there. KISS was so influential to me from 1978 - 1984... but Motley took things to a new level. Man, I need that 5th. band!
I do feel like Leppard is still sounding great and putting on excellent shows. The only problem is how uninspired their setlists are outside of their Vegas shows. It's tough getting excited about a 15 song setlist that will be 13 of the same songs they play on every tour.
As for Crue, I saw them on their last tour and they were downright horrible. It's a shame as I was a big fan of them back in the day and they always put on fantastic shows. These days though, Vince holds the mic to the crowd for the crowd to sing every other line while Mick Mars looks like a hologram statue off to the side. It's pretty painful to watch outside of the girl dancers.
As for Poison, they're still pretty good but again the setlist is boring as can be and they'll play the same 8 songs with CC's guitar solo and Rikki's drum solos. Their act never changes and we know they don't have any new songs to bring to the table.
15 years ago this would've been a great bill but I have little desire to see this now. I'd rather take that money and travel to see new bands that are making good new music. And that's coming from a big Leppard fan lol.
I agree, back in the 80's or 90's this would have been a must see for many of us, but unfortunately now their live shows (especially the vocals) fall well short of our memories of the guys in their prime. While I am not surprised the Crue didn't stick to their guns, especially considering the money, as Peter said, it is a bit of a slap in the face to fans who spent money believing it was truly their last opportunity to see them
