Duo Déjà vu​​​
 ​​Lysakowski and Hartka felt a profound sense connection and musical compatibility from the very beginning of their collaboration, and so aptly named themselves Duo Déjà vu.

The name also acknowledges those powerful moments of recognition and resonance that we experience when performance taps into something universal and great works transcend time.

Praised by Boston Musical Intelligencer for "their impressive lyrical talents (that) provided a kind of magic" Duo Deja Vu has performed together since 2011 in venues such as the Monadnock Center Bass Hall; the French Cultural Center; Boston Conservatory.

Committed to authentic and powerful performance that builds bridges, Cellist Rebecca Hartka's playing was described by the Hanoi Times as “magical and eloquent.”  Hartka has appeared internationally in Cuba, Italy, Vietnam and Thailand and in the Northeastern USA at Saugerties Pro Musica; the Frederick Historical Piano Collection Concert Series; Bass Hall Concerts; Columbia Universities St Lukes Concert Series; the 1794 Meeting House Concert Series; the French Cultural Center of Boston; the Dweck Center, among others.In 2014 she released her second CD Light & Shadow: Sonatas of Rachmaninov and Poulenc with pianist Alys Terrien-Queen. According to the Boston Musical Intelligencer they “ take this rich Russian music to new heights”, stating that their performance “ranks comfortably alongside several impressive readings by other major cellists.” Hartka released her debut CD "Folkfire" with pianist Azusa Komiyama in October 2010, receiving critical acclaim as well as radio play on both WFCR and WAMC Performance Place. The Daily Hampshire Gazette remarked of the CD that Hartka "emotes a passion worthy of a symphony orchestra" while the Greenfield Recorder praised her for having "a passion for precision that never imposes itself upon the music". She was the recipient of the 1993 Henriette Reiss Award for Outstanding Artistic Merit. Hartka completed a Doctor of Musical Arts in Cello performance at Boston University College of Fine Arts in May 2007, as a four-year recipient of the Deans Scholar Award, and an elected member of Phi Kappa Lambda, the National Music Honors Society. Hartka also completed a Masters in Music at BU CFA, and a Bachelor of Arts in Cello Performance at the Oberlin Conservatory and College. Hartka's teachers have included Leslie Parnas, Michael Reynolds, Rhonda Rider, Clive Greensmith, Andor Toth, Peter Rejto, Douglas Moore and Justin Kagan.
