"Litmus test" songs

I usually use trio jazz recordings im familiar with.Peter erskines recordings(palle danielson,john taylor).later are better.Bobo stensons war orphans is a great recording too.

Great question. I often use Ornette Coleman's "Ramblin'" to get the overall picture. Then I might go to a Schoenberg string quartet, like #4, to get the difficult space as a challenge. Then maybe all out baroque, like a Bach Orchestral suite. If I still like what I am hearing, I go to solo instrument pieces.

Last movement of Mahler's 6th by MTT and San Francisco. "The Drifter" on Justice Reocrd's "Strike a Deep Chord" and Odetta's "America" on the same record. "Poppa Was a Rolling Stone" on grp's "a twist of motown"; Jennifer Warnes' "If It Be Your Will" on "Famous Blue Raincoat"; "music for Organ, Brass and Timpani" on Sonoma. Karrin Allyson's "Blame it On My Youth" with Mike Metheny on flugel, I forget the album name.

I focus on different things on each. If it could be only one, it'd be the Mahler 6th because I haven't found a system that does that well that can't do all things well.

I always use these well recorded cuts:
. Diana Krall - A Case of You (Live in Paris)
. Rahsaan Roland Kirk - A Laugh for Rory (Inflated Tear)
. Art Pepper - Move (Art Pepper + 11)
. Terje Rypdal - Chaser (Chaser)
. Steve Hunter - The Idler (The Deacon)
. Otis Taylor - Resurrection Blues (White African)

And these not so well recorded cuts, but expect them to still sound good:
. Rory Block - Last Fair Deal Gone Down (Last Fair Deal)
. Paul Butterfield Blues Band - I Got a Mind to Give Up Living (East-West)

And this poorly recorded one which I only hope might not sound too awful:
. Reverend Horton Heat - Lie Detector (Holy Roller)

Paul Simon - Graceland - Boy in the Bubble, Graceland, Diamonds on the Soles of her Shoes

Steve Miller - Born 2b Blue - God Bless the Child

kd lang - Absolute Torch and Twang - Luck in My Eyes

Talking Heads - Naked - Nothing But Flowers
Talking Heads - Stop Making Sense - Burning Down the House, Life During Wartime

Miles Davis - Kind of Blue - So What (Columbia Mastersound) - only the bass in the beginning

Those will usually show up deficiencies pretty quickly. After those, I go to acoustic music, etc.
