This era was not only a great time because there was so much going on musically, it was also a time when the recording studio started to play a bigger part in audio recording. 16-track was first used in 1967 but it was a couple of years later when it became common. Engineers and producers started to understand how to record with more tracks and microphones. Experimentation was there but effects were still in their infancy so dry recording (i.e. no effects) was the norm. It was a simplicity they brought into the final stereo mix and hence, this era has some of the best, most honest recordings ever made. The mastering on this series is beautifully clean and with them all being recorded under those conditions, all the recordings give you a sense of being in the studio with the artists. The separation between the channels is as wide as you can get, the many people involved in the mix making full use of the pan-pots. As a whole on tracks such as Nilsson’s version of Without You or in parts when listening to the Hammond and vocal left-right balance in The Box Tops, it’s quite overwhelming.
