Should that be series'? Didn't want to risk it in the title.
So have there been any singles series announced for 2013 yet? I've been signed up to the Joyful Noise flexidisc series this year and it's been great – a clear flexidisc 7" from a great band (inc. tortoise, deerhoof, danielson, of montreal etc etc) every month and a fancy box for them all too. They're doing another one next year, I think you can get on the waiting list via their website http://www.joyfulnoiserecordings.com/joyful-noise-2012-flexi-disc-series.html?sef_rewrite=1
Any others? Physical releases are preferred but if there's any digital ones you'd recommend then go for it!
