So we're recording a few songs at a local bar, who dabbles in recording in their basement. I think of it as a gig business relationship development type thing. I barely know my ass from my elbow about recording, as I've dabbled with Reaper and an Alesis firewire mixer board at home. He told us he will be recording to both computer and tape. He asked us to bring 3, 1/2-inch 30 minute tapes, said they'd be about 50 bucks a piece. And using that information, my google-fu is failing me. Can someone point in the right direction as to what tapes I might need to purchase?
