Cyrille Aimée — "Off the Wall"
French-American gypsy-jazz singer with bossa instincts — sits between Stacey Kent and Madeleine Peyroux in your library, with a brighter rhythmic underside. Her covers album Move On is the easy entry; the seed track will radio into Brad Mehldau, Anat Cohen.
Bebel Gilberto — "Aganju"
Daughter of João — bossa with a soft electronic underlay. Closer to Tycho's atmosphere than to her father's sparseness. Seeds well into Marcos Valle, Joyce Moreno, then back into the Jobim canon you already have.
Hania Rani — "Esja"
Polish neo-classical pianist, lighter touch than Frahm, more melodic than Richter. The album Esja is a perfect dinner-table soundtrack; the title track radios into Joep Beving, Vikingur Ólafsson, Kiasmos.
Pasquale Grasso — "All the Things You Are"
Pat Metheny's protégé — solo jazz guitar with a bebop vocabulary that nods to Bud Powell. Sits cleanly between your Metheny and Jim Hall placements; if you like the latter for its restraint, Grasso is the natural next step.
Junip — "Line of Fire"
José González's full-band project — the same hushed Swedish-Argentine voice as his solo records, framed by drums and synth pads. Adjacent to your Bon Iver and Mazzy Star territory, but with more rhythmic propulsion.
