This is what I love about Steven Wilson, and musicians that just don't give a shit what they're fans think and say, and will do whatever the fuck they want, because they are the artist.
Steven feels like Guitar based music is heading toward a trend of slowly going away, or more that style of music, just as Jazz did. And I agree with him about where the music is going, Urban, Electronic, R&B. People still use the saxophone, he's just saying how The Saxophone was the guitar back in the age of Jazz, it was the solo instrument. Now that guitar took over that, in that era. In this era, something new is going to replace that Guitar as a solo instrument, and take over it's spotlight.
Then he goes on to respond to the Question asked by the interviewer, and is responding to the example the interviewer gave with the Rolling Stone Magazine, and gave his opinion on that question posed by Rolling Stone.
And I agree with him about Greta Van Fleet. I mean, they are supposedly the best, as they are popular, and they sound like Led Zeppelin, and rehash of that old sound. So in Stevens eyes, it's doing nothing new with it, and the bands that are doing some good interesting new stuff with the guitar is not mainstream. He acknowledges there is still music with guitar that is good, but his point is that those Guitar bands are not in the mainstream.
But, when he says, the new sound will have some electronic element, I think of bands like Polyphia, Chon, Plini, Arch Echo. These bands are putting these R&B, Hip-Hop, beats and putting them with Electronic sounds, and making guitar licks off of that.
But, it seems that he is upset that a band like Greta Van Fleet is popular while these bands like Polyphia whom are doing new things with Guitar are not popular. And to me, that feeling made him utilize other ways of making music, and experimenting with making a new sound, one that is liked by the masses, and that is the current electronic sound and style that his current album has.
