My favorite bands are the ones who grew up on stage. The bands who live for the show, not for the studio. Bands who played countless shows live, before they could even afford to record. If the band is a live band first, then a recording artist second, I'll get the maximum enjoyment.
Yes, I love excellent album production, great recording quality, and inventive songwriting. But most times, that kinda stuff doesn't translate well when it's a bunch of musicians who formed a group to write music, THEN go perform it for live audiences. When it's a BAND, an actual band performing for audiences, that knows what crowds like, and then go record an album, it works much stronger in the studio. Cuz they record albums that sound great, but also translate to a live setting better.
Hard for me to think of specific examples, but Edguy is the glaringly obvious one. Their albums sound like a jammin' band, but with great studio control and perfection. They don't sound stiff and artificial like bands recording to a click track, they sound natural and.... human.
