Robin Bharaj is one of my favourite photographers on Flickr. If you’re not aware of him, consider this a wake-up call. He shoots music photography, mainly, almost entirely comprised of medium format film (both colour and black and white) portraits. His recent set of pictures of A1 Bassline are some my favourites of his to date; I’ve embedded them below, and preserved their square format, as it only seemed appropriate.
You can view more of his work on Flickr, and he also has a Myspace presence. Thoroughly recommended.
