Agree with what @Tolga_Inam, your font choice is spot on! Love the elegance of the landing page. The hover interaction is beautiful also, I've seen it on a couple of other sites (Instrument http://www.instrument.com/ use it on their landing page) and it works brilliantly, but I think yours is even nicer with video! Well done, looks mint.
I think the sections that need more work are the about, discography and contact parts. I don't think you need to redesign much (I like the slide in from side) but just make some tweaks to make it easier to use. When you click any of the links, the actual box isn't scrollable, so set your overflow on the box that appears to scrollable then people can see all of the text. Also, I found it frustrating that the close button was all the way up in the top left corner, maybe move it closer to the box or better yet (I don't know if this is doable but worth a try!) make it so you can click anywhere outside of the box to close it. Last thing, maybe just add a couple of things inside the discography and contact boxes to make them slightly more interesting as there is a lot of blank space, some album artwork in discography and maybe a couple of icons for your social links might work?
Love the site though and think it's very inspirational as a one-page design, shows how you don't have to make everything parallax scroll nowadays!
