If you're American you might find it odd that we uk rappers have a different accent. To you it's totally new but to us it's just the way we talk. We apply the same flows, similar cadence, but... I find the american accent can rhyme with more words and stretch over the bars in a slower and comfortable way. My Nottingham accent (which is right in the middle of the UK)
tends to require a more number of words per bar to fill the bars. However I do find this style easier and closer to a new york style of rapping then London. London is slightly relaxed on the lips and less sharp in delivery.
Every day I share a song so I would like to know what you think of my Nottingham accent. At least it's different to what your used to and interesting to get your ears round.
One note: You say HOUSE AS HOWSE we say HOUSE as ASSSSS (no H) ;)
Here is some bars over the ROMANS EVENGE instrumental. Pure Nottingham accent.
