Merging and remastering two essential albums from free jazz saxophonist Marion Brown: his 1966 ESP album "Marion Brown Quartet" with trumpeter Alan Shorter, bassist Reggie Johnson and percussionist Rahied Ali; and his 1967 Fontana album "Juba-Lee" in a septet with Reggie Johnson, drummer Beaver Harris, pianist Dave Burrell, trombonist Grachan Moncur III & saxophonist Bennie Maupin.

Taking his quartet on a European tour in the fall of 1962, Coltrane's band with McCoy Tyner on piano, Jimmy Garrison on double bass, and Elvin Jones on drums performed in Graz, Austria at Stefaniensaal, the concert beautifully recorded by ORF Steiermark and here released as the first of two volumes, showing both Coltrane's lyrical origins and expanding free inclinations.

After introducing his new trio with pianist Paul Bley and double bassist Steve Swallow in two 1961 albums on Verve, clarinetist Jimmy Giuffre embarked on a tour of Europe, this recently discovered, well-recorded concert in Graf, Austria the perfect example of his unique concepts yielding intensely focused, harmonically challenging, rhythmically abstract, and exquisite chamber jazz.

Drawing on material from Billy Strayhorn, Thelonious Monk, Michel Legrand, Harry Warren, and Victor Young, the lyrical duo of saxophonist Alex Hendriksen (Swiss Jazz Orchestra) and double bassist Fabian Gisler (Jurg Wickihalder European Quartet) cite the art form of storytelling as central to their music as they reflect thoughtfully on the American Songbook.

The second album of piano works from Japanese composer Jo Kondo performed by pianist Satoko Inoue--a noted interpreter of solo works by Feldman, Ferrari, and Cage--here presenting all of Kondo's works for solo piano written from 2001 to 2012, alongside two early works from 1975, exploring a wealth of harmonic, rhythmic, and conceptual ideas from a diversity of projects.

The innovative string trio of Daniel Studer on double bass, Harald Kimmig on violin, and Alfred Zimmerlin on cello, develop focused environments of timbre, texture, dynamic and space, seemingly abstract yet incredibly concentrative and virtuosic interaction, here joined by Chicago trombonist and electronics artist George Lewis adding a 4th profound layer to their incredible conversation.

The long-running duo since 1987 of spouses, pianist Hildegard Kleeb and trombonist Roland Dahinden, are joined by Swiss-born/ Berlin-based percussionist & vibraphonist Alexandre Babel for an album of interweaving and contrasting instrumental lines, blurring the boundaries between contemporary music and improvisation through exceptional mastery and dialog.

With a superb septet of improvisers also versed in contemporary music, trumpeter Franz Koglmann presents sophisticated compositions that interject the concept of "solitude" in the three-part title track, alongside Koglmann compositions and Jimmy Giuffre's "Finger Snapper", using striking orchestration of trumpet, sax, clarinet, bassoon, oboe, french horn, cello and double bass.

An essential part of the New York jazz scene since the mid-80s, pianist Russ Lossing's compositions employ concept and space in unique and personal ways, as heard in these 8 original works performed with his trio of long-time collaborators, double bassist Masa Kamaguchi and drummer Billy Mintz, for an album of highly evolved and lyrically sophisticated music.
