My favorite has to be Bob Seger. Saw several of his concerts in Kalamazoo.
Saw Kiss back in the early 70's when they first started out. Man, I feel old!

I had the chance to see Electric Light Orchestra twice back when Jeff Lynne was still healthy. Such artistry and a unique sound.

Our musical tastes are all over the place.Rock would be Grand Funk Railroad,Alice Cooper,Cheap Trick.Pop.rock would be 3Dog Night,excellent show.Marie Osmond's Christmas show was excellent,along with Martina Mcbride.

The one I remember most was Ozzy in Duluth Mn January of 1982 just 2 months before Randy Rhoads died. But now it would either be Jamey Johnson or Chris Stapelton.

Saw Black Sabbath in the 70’s went to offer twice ozzzy my favorite metal band
Saw arosmyth twice favorite rock “show”
Saw Tim magraw and faith hill together before they were married liked the show a lot but my favorite country show was Neil McCoy

Not sure of my favorite, but Motörhead in 1987 was definitely the loudest!
My ears are still ringing

Favorite was Allison Krauss & Union Station back in 2014 or so.

The Who

Saw Ozzy on his first "retirement tour" in the early 90's. Great show! Think ugly kid joe opened with a great cover of sweet leaf! Man years go bye.
