In a 2014 interview with RockHall.com, Flemming was asked if he had a favorite METALLICA recording, one he was most proud of. He responded: "I would say 'Welcome Home (Sanitarium)' on 'Master Of Puppets' is probably one of them. That's the one with the mono-stereo — and I'm a sucker for that kind of shit, you know, when you sit with headphones and you go, 'What the hell was that?' ... There's a lot of those, I think theres a lot of songs on all three albums that I'm really proud of. I think 'Creeping Death' on ['Ride The Lightning'] was probably where we really nailed the METALLICA sound. That whole epic kind of thing. It's also a very, very good song — that, of course, has something to do with it. We all had this feeling where what we were doing, we were going to go a long way. We were going to change music history. And I think that was the project from the beginning. Also, you know, we think about it and they had their own thing going, and they had this tremendous energy, that, kind of, is a trademark for the band. They don't want to rely on MTV to play their videos, so they didn't make any videos, because they didn't care because that wasn't important to them. It's been like that with METALLICA always."
