All I can envision when I hear this is if they made a retro style cop show in 2024 and this was the theme song. Don't know if it was meant to have a throwback feel, but I dig it.
No it is not a sample. It's John Pattituci playing the higher "Paul Jackson" style bass lines on the first section and then he goes to the low bass on the B section. Then he takes a Solo on his 6 string bass. We made the track together.
