Trellion n Sniff less go.
UK been killing it for ages, still quite a small scene but it's been growing. These guys helped pave the way for any UK rappers your hearing now.
Kyza Smirnoff. Anyone remember Terra Firma?
Klashnekoff was probably more known but i always preferred Kyza myself.
A UK rapper that definitely never got enough props was
Maxi Jazz from Faithless. Faithless were big, but his raps were slept on.
Skinnyman? Legendary track right here. Man was homeless for 18 fucking years, you don't get more street than that brev...Wonder what happened to him.
Task Force
Jehst is still doing it.
Task Force are too actually, they released an album last year (?) May have been this year..
Best UK rappers for me these days would be, in no order..
Lee Scott. "Lee Scott is your favourite UK rappers favourite rapper. This is fact, as it is common knowledge that there isnt really anyone who can, word for word, match his wit and incredible turn of phrase. Lee Scott is blessed with the ability to communicate incredibly complex story lines and concepts with such ease and clarity that you almost forget that everything he is saying is actually rhyming to perfection. "
Not his best known track but i'm loving that one at the moment, "Grab the mic like raps Marshall Applewhite". This guy has an unnerving consistency of both quality and quantity, he's got over 20 releases to his name and shows no signs of slowing down, he released two albums last year (one of which, "Tin Foil Fronts" won Wordplay magazines album of the year), and one album so far this year, which was entirely produced by
Dirty Dike.
Jam Baxter. One of the best rappers i've ever heard. Period. Nobody is even close to doing it like he does, go submerge yourself in this mans work and come back and tell me otherwise. Flow, imagery, versatility, consistency, originality etc etc Jam Baxter is a heavyweight from any way you're looking at him.
Ed Scissortongue.
May be relevant to OP's interests Should be at the absolute forefront of British music imo. He's one of the rillest in the game and together with Lamplighter they're one of the illest and most progressive combinations in music.
If you've been clicking the links you've probably noticed most of them go to High Focus records, which is probably the best place to find UK hip-hop at the moment, there's quite the variety of rappers on there.
Blah records and
Mouse Outfit are worth checking out as well.
