I don't really do much writing anymore, but here's a bunch of things I've done in the past.
I used to write about Music Videos for Promonews, now I just hassle directors for Q&As every so often.
I used to write about Films for Highsnobiety. You can read them here.
I used to write about Weird History for Mental Floss. You can read those here.
I used to write about Music Videos for Word Is Cheap, you can read that here.
I used to review music for The 405, which you can find over here.
