Classic Sound: Pink Floyd's Dark Side of the Moon

One of my favorite albums of all time, DSOTM is arguably the best engineered album ever. The mixes and effects, the loops and certain sequences are just amazing especially for the time. This album stayed on the billboard charts for something crazy like 15 years after its release. Absolutely timeless, I still listen to this album for inspiration. Here's a great documentary with all 4 band members and their engineer Alan Parsons.
