Gary Numan
Gary Numan's most recent album was 2017's "Savage (Songs from a Broken World)."
CBS News' Jake Barlow asked Numan, "The music industry is constantly changing and so is the music. How does one survive?"
"You need to be adaptable," Numan replied. "I think you need to be aware of the new technologies that come along. A lot of talk about the terrible state of the music business, I think, is very misguided. It tends to be looking at sales only in some respects. I feel it's a very narrow way to look at it, because as album sales have gone down, a lot of advantages have come along which, if your adaptable and flexible, you can absorb these new things. I feel in some respects it's a golden era"
Gary Numan
"There are a number of veteran artists who tend to stagnate and stay in their golden period and milk it for what they can get," Numan said. "I personally find [that] to be shameful. I've always thought that if you have a long career, you have to earn it, and you shouldn't be based on something you did 30 or 40 years ago.
"I try very hard with every record I have ever made to move on and progress, to find new things and new sounds. I haven't always succeeded but that's been the intention – to move forward and not dwell on the past. But it is a difficult thing. There is a part of the audience that wants to keep you anchored in the time that they found you and keep reliving that moment forever. … You're trying to find ways of moving forward without losing people and reinvent yourself in a way that resonates with new people and perhaps the old people. It's a difficult thing to do. I gave up figuring it all out!"
