This. SOme of those artists I've never heard of so I can't even comment. The one that stuck out at me is KISS. I'm not saying I know every single tidbit there is to know about KISS but I have ~
never~ ever heard anyone in the band say
anything about ELO (good, bad, influential, etc). That's not to say that ELO weren't somehow, someway, maybe had some bit of influence over the early roots of KISS, but I've never seen it (and would love to see a source if there is one). Beatles, The Who, Led Zeppelin, Alice Cooper, NY Dolls, Slade.. those bands played key roles in the shaping of KISS both as a band and with the individual members. ELO? *shrug*
And I agree with TS's sentiments. I really don't recall hardly anyone ever saying ELO was a key influence. Doesn't mean it's not true, but it's something I've never seen or noticed.
As for ELO itself, it's it kinda common knowledge that ELO = Jeff Lynne + a group of guys that he tours with? I could be wrong, but I'm pretty sure that I've read that Jeff plays nearly every instrument in the studio and uses the rest of the band for videos, live appearances and tours. Jeff has a ton of talent, no question. His work as a producer is also top notch from anything I've ever read about him. I just don't see him (or the 'band') as being that influential though.
