Jamaican Queens are neither Jamaican nor are they queens, but the name suits them just fine as the Detroit-based band are self-proclaimed "Detroit Trap Pop." What divas! Never mind that such a title is a confusing bundle of styles, pay close attention to the feeling such a category conjures. Honestly, it's a pretty accurate description of their music.
To help you understand, I'll back up just a little. The first I heard of Jamaican Queens was a remix they did for a Detroit hip-hop duo called Passalacqua. Take a listen, there's no question about that being trap. Then, I learned that the group is composed of former members of the band Prussia, which you could consider them pop's twisted sister. Lastly, being that Jamaican Queens are from Detroit, one may surmise that they are influenced, directly or indirectly, by some sort of deep techno like Jeff Mills, raunchy glam rock like Iggy Pop, or something of the J Dilla persuasion.
If you take into account all of the above, Jamaican Queens makes as perfect sense for a band, as "Detroit Trap Pop" makes as a genre.
At any rate, genre be damned, none of the name calling matters unless the music is good. It should speak for itself. So, be your own judge and scope out the newest singles on their Bandcamp, and if you've been longing for a "very specific sort of weird. Niche weird!" (yes, that's a Workaholics reference), just check out their Tumblr. Take it sleazy.
