A limited edition half speed mastered pressing of Switched on Bach by Walter Carlos

This item has been sold.


Offered for sale is a limited edition half speed mastered audiophile pressing of Switched-On Bach, by Walter Carlos.

About this copy:  This copy of Switched-On Bach is one of the CBS half speed mastered series, which was in print for only a short time in the early 1980s.  The cover is VG++, with just traces of wear at the corners.  The record is M- and looks to have had little, if any play.  The generic CBS Mastersound insert is included.

Background: When first released in 1968, Switched-On Bach was a revelation, as it put a new spin on both classical music and the Moog synthesizer, which until that point had been largely found in electronics laboratories.

The album sold well and made the Moog cool and made Walter (now Wendy) Carlos famous.  It’s still one of the best-selling classical LPs of all time and the first ever to be certified platinum.

This particular pressing was part of Columbia Records’ short-lived (1980-1983) audiophile series, in which they released a number of then-new and vintage titles in high-quality, half speed mastered editions in order to compete with Mobile Fidelity and Nautilus.  These records were mastered with both the tape deck and the cutting lathe running at half speed, which produces deeper bass and better imaging than standard pressings.  In addition, these records, which sold for a substantial premium over the regular pressings of the album, were pressed on high quality virgin vinyl.  Mobile Fidelity’s audiophile pressings are better known than those from Columbia, but Columbia’s half speed mastered pressings are, for the most part, exceptionally good ones, and this album is no exception.
