Spotlight Feature: Carishma

Pop singers are a dime-a-dozen, but it isn’t every day you come across one like Carishma, who has the seductive beauty of Pussycat Doll Nicole Scherzinger and J.Lo!

MJ is always scouring the ‘net for young talent and it’s safe to say – Carishma is worth getting to know! So, we caught up with the Jersey girl about her career, her musical inspiration, what it was like working with Timbaland, and so much more!

Get to know Carishma:

MJ: Your single “Glow In The Dark” is on iTunes and your music video was just released and has over a half million views — how does that feel?

I loved recording that song with Rodney Jerkins. I feel like it’s a really relatable song about first love, so to see it connect with so many people has been really exciting. At the same time, I am at the beginning of my journey so I am looking forward to putting out some more music and showing people other sides of myself. It was also great to work with someone as talented as Taj Stansberry, the video director. He also did J.Lo’s “On The Floor,” which has the 2^nd most views of any music video on Youtube. He was great to work with, and really helped bring my vision to life on screen. It really portrays what my romantic night on a beach would be.

MJ: Tell me what your life is like now?

My life really hasn’t changed. I work really, really hard. I worked really hard during college at NYU and having recently graduated, I’m working just as hard at music but I love it so much more! Having a career in the music industry is a lot more work than most people think it is. It’s not just photo shoots and talking to media. I’m in rehearsals, in studio, recording and writing songs, doing vocal coaching, learning choreography, talking to my lovers on fb and twitter, and to bloggers like you!
