Original Cast Album: Company

It's impressive to watch a gaggle of Broadway's best, at almost the exact moment the clock moved from the 1960s into the '70s, take their places in a featureless recording studio to make history. The original cast, the orchestra players, the sound engineers, composer Stephen Sondheim, and session producer Thomas Shepard demonstrate more than great talent and love for what they're doing. They give a master class in how to listen, how to give and take direction, how to hit the creators' target. Near the end, when Ms. Stritch belts out a solo for the ages at 3 a.m., the producer criticizes her delivery, and I wanted to smack him! But I'm not a theater person, unlike the phenomenal troupers who kept soaking up instructions and doing more, more, more takes till everyone was happy. They did it right.

If you own any original cast recording of a Broadway musical, I recommend this behind-the-scenes look at how one OCR was made.
