Direct 2 Disc

I own the Sheffield Labs Harry James d2d LPs, and they are excellent.  My favorite d2d record, however, is American Gramaphone's Glenn Miller Orchestra LP from mid to late 1970's.  Outstanding in every respect.  If you enjoy the Big Band sound, try to find a copy and give it a spin.

Sheffield labs. Thelma Houston "Pressure Cooker" is my reference album that I judge all others albums by. 

M&K Realtime Records "For Duke" is my reference and has been since its release in the late 70's. Fantastic recording.

I agree, "For Duke" is on my short list for demo discs, along with "Fatha" another fantastic M&K D2D recording.  If I put together my short-list of demo records, it would contain:

TBM-Yamamoto Trio-Midnight Sugar (1st pressing)

???-Clark Terry-Alternate Blues (Analogue Productions or some        other company reissue)

East Wind-Great Jazz Trio-Direct from L.A.

Concord Jazz-LA4-Just Friends

Analogue Productions?-Doug MacLeod-Bring it on Home

King Records-Mozart Clarinet and Horn Concerto-Gervase de Peyer, Barry Tuckwell, Peter Maag (Japanese reissue of a Decca original)

Columbia-Duke Ellington-Blues in Orbit (1959 stereo recording-proof
that the state of the art in recording has not advanced much in 60      years). 

Clarity Recordings-Claudia Gomes-Salamandra

Audioquest-Tuxedo Cowboys-Woman of the Heart

For those not familiar with the history of D2D LP records, this is what I read some time ago.

Doug Sax, and possibly Mayorga, was listening to some favored 78 records.  He was impressed by the presence and sense of "aliveness" heard in many of those, but not typically experienced with LPs.  Upon consideration Sax realized they were recorded directly, without the intervention of a R2R master tape copy as had become standard practice with LPs.  So he experimented with a directly recorded LP, and the rest is history.

That history now includes the several wonderful recommended D2D LPs in this post.
