Running for Dummest question EVER

Half Speed Masters from Mobile Fidelity Sound Labs were what I was referring to above as "MFSL Records"

There's plenty for sale here, and they are generally worth it, but MFSL records is gone (again), I think.

Try Tower of Power "Direct" from MFSL. Direct from the horns to the mics, to the cutting lathe, cutting at half speed - about the closet live reproduction you'll get.

All albums are virgin vinyl too. I sold all mine (about 40 in excellent condition) about 6 years ago for $1,200. My first AGon deal.

That's what MFSL Records were all about. Most information in a given space, like the Track Record.

Metrlla - I'm wrong and right.

I'm right in that MFSL was pressed at half-speed from the original master tapes, as Ferrari says, but wrong in that Tower of Power Direct (and the Track Record) , were indeed Sheffield Labs records.

I'm fairly sure the Sheffields were half-speed masters too.
