You think a drake song will ever reach 30 BPM???
60? 120? 240?
Nothing
special.
The content is though.
Having a drum machine back in the 90s gave room for experimentation. Since it was limited, bringing the bpm down to get the desired feel for faster percussions was a normal practice. Or to perfect the idea in ones imagination you would slow the tempo real slow, then speed it back up til it felt right (for back then). BUT.......some people actually liked the feel of the percussion sounds when they sped the tempo back to a normal state, but they loved the idea of other sounds they messed with while the bpm was slowed. So it became simple mathematics, to make something do what it wasn't meant to do. The outcome is guys like Prince, Jam and Lewis, Teddy Riley, Timbaland, Dr.Dre, and others developing their own style from it. Innovation wins every time. It's like going into a temple looking for gold, and coming out without gold, but a mindset worth more than gold. Peace!
Want to add to this a story Jam and Lewis (one of them) said in an interview in a book. They were talking about the many mistakes with the equipment breaking down and being ragidy that brought hit after hit. They made a midi hook up mistake one time and the drums were playing the rhythm of a sounds played on the keyboard. They switch the drums around and BAM!!!! They ran with it. Timbaland may not have told you his story, but even back then I knew what had happen because it had happened to me, also.
Now take that happening and apply that to how developers think in todays time of perfection in the computer world. You have every glitch tool in
the world...........that does nothing more than what you can do in your DAW without a vst or plug. They made it easy for you to jump past those errors by creating them......for some $$$. The same way delays and flange and chorus and other
effects were experimentation and discovery. And we use them today thinking one outdoes the other.....but it all comes from the same
concept from the discovery of "MISTAKES MADE" or being curious.
With that said, it's not about what's next as in sound, IMO, but how can we find error. Because error is correct in these days in time. Where should our curiosity be. How can we make things do what it's not meant to do to discover a new way of listening to music of any solid genre. Because that's why eras of music change. Even in Jazz music today, there are so many sub genres of it do to curiosity. You say Jazz music, you have to ask what type....swing, big band, smooth, acid, ect.
