I'm a big Van Halen fan. Finally got to see them in 2015 when they played the Hollywood Bowl with Dave. I believe it might have been one of their last shows before Eddie died. Great show even though all were showing their age.
I did prefer the Dave albums. At first, wouldn't even listen to the Hagar albums. Took me a few decades to really even give them a chance. Then I looked at them more like a different band. The band was more mature. Lots of good songs, some sappy love songs unlike the raw rock of the Dave albums.
Definitely Eddie's fault that the band pretty much died. Fire Dave after their biggest hit album, then somewhat the same story with Hagar. He was somewhat friends with Howard Stern, used to call him. Howard even said it was like talking to a genius/lunatic.
Too bad, but many bands have the same story and just conflicting egos.
