Does anyone know if Link Wray allows taping. The man is coming to town
and I would definetly love to tape.
If anyone has any idea, please let me know.
thanks

In March, Joe Satriani will be playing one date in Auckland, NZ, and
he'll spend the remainder of the month touring Australia. I'd love to
hook up with some Aussie/NZ tapers for any of these dates. Please
email me privately if you can help out. I've got lots of Satch to
trade.
Thanks,
Jeff

Subject: 3:1 Rule
Date: Thu, 27 Jan 2005 20:19:30 -0500
Nick,
I'm afraid I strongly disagree. The 3:1 rule applies ANY time one opens a
mic. I suggest a quick review of Everest's Master Handbook of Acoustics Pp.
313-316 and The New Stereo Soundbook Chapter 8 ("Audibility of Reflections")
by Streicher and Everest for a thorough discussion. To summarize, the three
to one rule not only apples as Lou Burroughs defined it, but it exists for
reflected sound as well.
Without proper placement, the floors, ceilings, and walls provide reflective
surfaces which introduce comb filters. Colin said he was 28' back in a
"small club." To avoid phase cancellation and comb filtering, he would have
to be 84 feet away from any reflective surface. The mic placement he chose
was fitting of a much larger room. Also, as the distances increases from
the direct source, the relative volume of the reflective sources increases.
This phenomenon only serves to aggravate the situation, leaving the
recordings awash in reflections and bar-chatter.
But look what happens when he theoretically places himself 8-12 feet in
front of the stage; the distance based on microphone geometry and the 21'
stack spread. The 3:1 rule suggests walls should be 24-36 feet away. This
sounds much more like a small club.
Bottom line, 3:1 rule always applies. Sound is simply a matter of physics.
Understand the physics, understand the key to better recordings.

I too have heard that Blumlein will "expand" or "decode" into surround. One
of the commercial releases I recorded has tracks recorded with a Blumlein
pair if anyone wants to check it out (I don't have such a system, so I can't
offer an opinion). Buying the CD is much cheaper than buying the
microphones or a surround system...
Copland et al. Cello Works. Terry King
Music and Arts. CD 1076
Tracks 1, 2, 11, and 12 recorded in Blumlein
Available at Amazon in the classical music section.

I'm trying to find contact info on these tapers. (Russell & Michael Brand)
They used to be very active on DAT head. They have some BB King masters
that I'm trying to get. If anybody here knows how to reach them, please let
me know, thanks.
