When I first heard this, I was picking up this 12" vinyl from a street vendor at Camden Town in London in 97. It's the most amazing DnB track ever produced. It's "Your Sound" by J Majik. I think he was not even 20s at that time. It's still my favorite track! If I ever need to pump myself up in excitement, I just need to crank this up to 11 and it always do the job.
