Lizz Wright

Through an inimitable voice that The New York Times touts as, “a smooth, dark alto possessed of qualities you might associate with barrel-aged bourbon or butter-soft leather,” Wright sings with a soaring reflection of the cultural fabric of America. She lies beneath the script of human history transcending social divides with an offer of love and deep sense of humanity. Her music accepts the beauty of reality and a collective experience of belonging.

Rachel Eckroth

Pianist, singer, and composer Rachel Eckroth is more than a musical chameleon. Her shapeshifting is so astonishingly dramatic that there is no upper limit to her creative identity. She possesses a magical ephemeral creative style whether she’s accompanying on keys with stars such as St. Vincent or Rufus Wainwright; or producing dream pop for vocalist Sy Smith; or singing folk songs with guitarist David Garza; or ripping through a jazz standard as a talented piano improvisor.

Edmar Castañeda & Grégoire Maret

Harmonica player Grégoire Maret, born in Geneva in Switzerland and harpist Edmar Castañeda from Bogota in Colombia are two remarkable musicians. Each of them came from his respective country as a callow teenager, and settled in New York and each has re-written the rule-book for his respective instrument, both of them unusual in jazz; Castañeda and Maret have re-defined what the harp and the harmonica are capable of….

Becca Stevens & Attacca Quartet

Nearly a decade ago, singer, songwriter, multi-instrumentalist, and 2021 GRAMMY® nominee Becca Stevens was approached with an intriguing concept: to reimagine a selection of her songs with string arrangements for a performance at San Diego’s illustrious Mainly Mozart Festival. The concert would also inspire a career-spanning passion project—one which blossomed alongside her relationship with Nathan Schramm member of the GRAMMY® Award-winning Attacca Quartet.


In August 2020, amid the seemingly insurmountable restrictions of a global pandemic, five unique musical spirits gathered in the stunning countryside of western Portugal to record an album together. Living and working under one roof, Justin Stanton, Gisela João, Michael League, Louis Cato, and Becca Stevens were led by one simple guideline: that each participant must co-write a song with one another. The result is Mirrors: a dynamic and introspective collection of songs.
