Across selections gathered in this rare promotional release, ECM’s 2018 landscape holds together by an invisible underground current in which every melody becomes a thread whose destination remains mercifully uncertain. John Surman opens that map on Invisible Threads (ECM 2588). In “At First Sight,” his soprano enters the upper air, stitching daylight to the needle-eye of time. Thomas Strønen’s Lucus (ECM 2576) carries this paradox inward. “Time Is A Blind Guide” separates filaments of interpretation from emotional moonbeams, suggesting that guidance may begin precisely where sight relinquishes authority. On Contra la Indecisión (ECM 2582), the Bobo Stenson Trio gives Silvio Rodríguez’s “Canción contra la indecisión” a unified tenderness. Deprived of words, the song discovers another grammar in touch: melody becomes a hand passed between players, each musician safeguarding its meaning with tenderness.

The human voice enters this space bearing the knowledge that affection often recognizes itself through distance. Norma Winstone transforms “What Is A Youth?” on Descansado (ECM 2567) into a dark lens for parries of desire, her phrasing suspended between confession and the private afterimage of confession. Elina Duni’s Partir (ECM 2587) makes departure even more elemental. Domenico Modugno’s “Amara Terra Mia” opens as many doors as it has words, then leaves each one trembling on its hinges. With the scene stripped to voice and guitar, ancestral ground becomes an umbilical memory severed for the sake of itinerancy. Uncertainty shadows every vocal step, while the guitar offers a small republic of earth beneath it. Elsewhere, Ketil Bjørnstad’s A Suite of Poems (ECM 2440) finds a more mischievous form of displacement. In “Astor Crowne, New Orleans,” Anneli Drecker steers a blues-inflected drinking song through whimsy, turning the tavern into a temporary country whose citizenship lasts only as long as breath can carry a phrase.

Other performances navigate by enlarging the sky within the instrument. Shinya Fukumori’s For 2 Akis (ECM 2574) begins with “Hoshi Meguri No Uta,” Kenji Miyazawa’s “The Star-Circling Song,” whose original words enlist Polaris as a guide through the visible universe. Its historical aura reaches toward Japan’s interwar preservation of folk culture, but Fukumori approaches the past as a living correspondence rather than a museum seal. Walter Lang’s lyric curiosity illuminates the route, and Matthieu Bordenave’s vulnerable tone gives stardust a pulse. Nicolas Masson pursues a related bond on Travelers (ECM 2578), where “Gagarine” moves through continually altered currents. The saxophone exceeds the boundary of the body producing it; song sustains the instrument until player and horn dissolve into a shared horizon. In Jakob Bro’s Returnings (ECM 2546), “Strands” constructs a tesseract inside the floating mind. Its geometry seeks purchase without demanding surrender, tethering consciousness to an elsewhere whose dimensions can be heard but never entered whole.

Ground and altitude keep exchanging masks. On Kit Downes’s Obsidian (ECM 2559), the floating arpeggios of “Kings” score their images with a palette knife. A horizontal path tilts upward against gravity, weighted by Downes’s contrary motions and his spontaneous deference to suggestion. Somewhere inside the music, a boy crosses hills in search of a destiny no one has selected for him, leaving an audible trail for those whose blindness has sharpened other forms of vision. Mathias Eick’s Ravensburg (ECM 2584) assembles “Children” within the puzzle logic associated with the album’s Southern German namesake. Eick’s singing voice extends his trumpet’s long residence in the throat. Håkon Aase threads his violin through the deeper channels Eick carves, while Andreas Ulvo and the rhythm section give the terrain a responsive consciousness.

That self-awareness darkens and intensifies across the instrumental ensembles. “Thirteen,” from the Andy Sheppard Quartet’s Romaria (ECM 2577), lets guitar swells recover the spacious grace once brought by Terje Rypdal to Ketil Bjørnstad’s The Sea. Kristjan Randalu’s Absence (ECM 2586) works through briefer inscriptions; “Lumi II” reveals process by granting Ben Monder’s painterly imagination room to wander beyond the frame. Circularity becomes an ethical discipline in “Modul 60” from Nik Bärtsch’s Ronin’s Awase (ECM 2603). Tender and shadowed, this interlude uncovers depth through return. Marc Sinan and Oğuz Büyükberber fracture that depth on White (ECM 2558). “there I,” the opening section of Büyükberber’s five-part suite, releases a free-jazz kaleidoscope of windows nested within windows.

Arild Andersen’s In-House Science (ECM 2594) brings the experiment to combustion. “Mira” rises from the bassist’s luminous tone before Paolo Vinaccia and Tommy Smith drive it toward a brightness nearly hostile to vision. A fleeting uplift vanishes before it can harden into reassurance. These powerful characters merge through radical attentiveness, exchanging leadership with the fluidity of thought moving between minds.

Steve Tibbetts closes this constellation by bringing cosmic scale into the foreground. On Life Of (ECM 2599), “Life Of Emily” trades earth for flesh, with fatherhood refracting sunlight through rain held just beyond arrival. The album’s invisible routes finally converge in the fact of another person, whose existence redraws the map simply by entering it. Perhaps this is what all these musicians have been circling: every note entrusted to the unknown is an act of parenthood, responsible for a future it will never see to full fruition.

Special thanks to David Wakeham for bringing this album to my attention.
