Frank Lowe – Black Beings

27 Oct

Frank Lowe - Black Beings DS531u front

Recorded in 1973, Frank Lowe (tenor saxophone) pulled in Joseph Jarman (soprano and alto saxophones) and William Parker (bass) to fly into the eye of free jazz. Lowe was into the music after John Coltrane’s album ‘Ascension’, and the influence and impact can be felt right through. Lowe went out on a musical limb here; the genre was not a long-term residence for him.

Black Beings serves as an historical document and stopping-off point in the musical legacy of Lowe, showing a rare side of the musician.

This is another DY encoded album from the ESP label and in its original album length version, and not the recently discovered ‘extended’ version. Obviously the fact that they discovered the uncut version in the vaults doesn’t mean that it was quad, but the thing about the ‘remastered’ release is that it is compressed and has suffered from obvious eq-tweaking to make it sound ‘clearer’. And it’s the heavy-handed eq-ing that can permanently damage the encoding, hence the use of the original length version.

Recorded live March 1973

Vanguard DY Demonstration Disc

21 Jan

Vanguard DY Demonstration DS459u front

Whilst doing final testing on the new DY decoding process i was contacted by ‘Captain Beyond’ who had just acquired a DY demonstration LP and wondering if i’d care for a transfer of it. What perfect timing. It is interesting to note that the track listing is the same as Vanguard’s later SQ demonstration disc released some time ago: DS137f

As many people have no idea how DY/EV-4 sounded, given they were not capable to reconstruct the original four channels due to the basic nature of the matrices, i thought this was the perfect time to do a two disc release, one using DY/Unicorn and the other using an accurate software emulation of the Dynaquad adapter.

One small point regarding Disc 2. The Dynaquad adapter did not do any processing to create the front channels so they are just the raw stereo track. That means that they can be used for any experimentation you may want to try.

It would be interesting to hear any comments……..

The Flames – The Flame

The Flames - The Flame DS418f front

This album, in a good condition, is reasonably rare. There was a CD release  but it used a so-so copy of the LP as it’s source. This release is from a rarer limited release CD that used the master tape as its source.
