I have an old MB transcription book published in 1981 in Japan, titled :
"MB perfect transcription" -- now, discoutinued.
It contains 13 solos during the period around "Brecker Bros. 1st" - "Heavy Metal Be-bop".

In this book, there is 2 pages of interview article at Dec.1980.
MB talked some interesting matters. Because the copyright does not allow to show all, so I summarize some tips about his technique.

[About Mouthpiece]

Asked about MPC, MB answered "Dukoff D9"
This period corresponds to the album : "Detente(Brecker Bros.)" or "Blue Montreux"
After a short period, MB changes MPS to Gaudala.

Dukoff at those days differs from today's that at manufacturing and at material.
It was very difficult to meet a "good" Dukoff because of the individual variation.

Maybe, MB had tried numbers of Dukoff at numbers of shops.

[Influenced Players]

MB's answer : Cannonball Aderley, Eric Clapton, George Benson, Harvey Mann

The interviewer (maybe unsatisfied because there was only 1 sax player ??? ) continued to ask
"How about Coltrane or Joe Henderson ?"

For this annoying question, MB answered "--- Obviously".

However, I have read the same questions at some other interviews.
MB's answer seems not to be consistent.

Once, "Dexter Gordon", and another case, "Stan Getz".

I understand, MB listens everything, and gets everything.

[About high speed fingering]

The interviewer continued to ask the ultimate question ; "how about your fingering on speed phrase ?"
MB's answer was dry. "That's top secret."

However, finally, generous MB gives a hint, that he has more than 1 fingering form for 1 note. That "strange" method was optimized after a long time trial.
There is no more concret information about this "method".

I suppose MB is saying in case of altissimo phrase fingering, upper than E (C.T.=D).
According to a phrase, he may change the fingering.

[Advice]

In those days in Japan (maybe at all around the world), so many sax players were trying to imitate MB solo.
The interviewer asked MB to "give them an advice".

I was forced to make a bitter smile, when I read MB's advice:
"It is good to play with my record"
No trouble, if you can play with MB.

Finally I found a practice method.
That was --- to play casette tape in half speed. (--- I had a special recorder)
Although the pitch went 1 octave down, I could catch up with half-speed-MB.

Now, we are in the digital world. With PC, we can get any speed with pitch keeping.
It's easier than ever.
