I can give you specifics but there is a bunch from these cats.  

Hi guys, apologies for not responding sooner; been strung out with work.

Thanks for all the suggestions, great response 👍

Some I'm already familiar with: Coltrane, Davies etc, some I'm definitely not familiar with. You've given me loads to pour over. I'll be adding them to my Qobuz for a good listen as soon as time permits.

Other albums I love - Stanley Turrentine with the 3 Sounds "Blue Hour" and the Dexter Gordon - "Ballads"

My formative years as a teenager were the 80s, and 90s as a young adult, so grew up with "alternative" music; what I also have found are some bands who use this heritage and fuse it with some Jazz sensibilities. Anyone interested, check out the band "I just Came Back from the Moon"

Thanks again guys, genuinely appreciate this 👍🤩

Unquestionably, improvisation is the defining element of jazz.  
These artists communicate in real time.  
This fluidity of expression when listening to music like late-‘40s Dizzy Gillespie or Charlie Parker through mid-to-late-‘70s music by The Art Ensemble of Chicago or Anthony Braxton (and everything in between) is unique to this music.

Some additions similar to MRQ that I didn't see listed above:

Brent Jensen: The Sound of a Dry Martini  (basically a Paul Desmond tribute)

Ben Patterson: For Once in My Life

Houston Person: Live in Paris

Hank Jones: For My Father

As @petaluman said, check out much of the ECM catalog, past and current.

While most of it will be more 'progressive' than the Magnus Ringblom Quartet, it will also be somewhat introspective in tone and mood, like the Magnus Ringblom Quartet.

In other words, despite a lot of the artists on the ECM label being as quiet sounding, it will still have more fire in the soling, complexity, and get a bit more ’outside’ (without being avant-garde).

Here’s a short list of what this great label has to offer:

Eberhard Weber - Colours of Chloe. Later That Evening, Yellow Fields

Pat Metheny - Bright Size, Watercolors, As Falls Wichita, So Falls Wichita Falls

Craig Taborn - Daylight Ghosts

Jan Garbarek - Jan Garbarek / Bobo Stenson Quartet, Of Mist and Melting

Tord Gustavsen - Extended Circle, The Well

Azimuth - Depart,

Ralph Towner - almost anything with Towner on it is worth checking out. As well as his own recordings, he guests on a lot of other recordings.

Ketil Bjørnstad, David Darling, Terje Rypdal, Jon Christensen - The Sea,

Sidsel Endresen - Exile

Anat Fort - A Long Story, And If
