What legal power do they actually have in this situation?
Don't believe they have any. These companies purchased the rights to press their albums. I mean they can get their label to bitch out the companies (don't think SRC has done anything seriously wrong at this point and will give them the benefit of the doubt), but I don't know what that will do in the end.
According to my cousin who is good friends with a guy who presses for Hot Topic, he's trying to get something together for a pressing coming in June. Other than that, I don't think I have ANY hope in this shitty situation.
I stood by RJ for a long time on this issue because I have always received top notch quality vinyl from MTS and he always responded to my emails. He even sent a handwritten note thanking me for an order I did on an out of stock self-titled blink vinyl. I can no longer stand by him. If I were him I would have said long ago, I fucked up. I would reply to every email, tweet, call, facebook message, etc, I got concerning the situation instead of going into hiding. He should have been releasing public statements at least once a month (if not more) concerning the situation. In fact, he should have probably went right ahead and refunded everyone's money until he actually got the vinyl in his hands and then guaranteed those people who did buy ahead of time a significant discount and a raincheck that would give them first dibs on the vinyl. He's ruined his reputation for life and he's probably lost trust from a lot of bands and professionals in the industry. FUCK THIS DUDE.
