There are a lot of New Sincerity rappers, but it's tough to top Ghostface in that department.
Case in point: the Ghostface f. Jadakiss and Comp - Run video, in which Ghost wears one of the most amazing and New Sincerity hats ever worn by any man ever in all times. Not that it's hard to find Ghostface wearing something New Sincerity.
Not to mention lyrics like this one, selected almost randomly from "Supreme Clientele:"
Hit Poughkepsie crispy chicken verbs throw up a stone richie
Chop the O, sprinkle a lil' snow inside a Optimo
Swing the John McEnroe, rap rock'n'roll
Tidy Bowl, gung-ho pro, Starsky with the gumsole
Hit the rump slow, parole kids, live Rapunzel
but Ton' stizzy really high, the vivid laser eye guide
Jump in the Harley ride, Clarks I freak a lemon pie
And here's a bonus treat:
