Described by The New York Times as an "astonishingly good pianist", Tatjana Rankovich is committed to continuously expanding the boundaries of the traditional repertoire, constantly searching for and discovering new contemporary music and devoting her interest to performing rarely heard works of the past. An innate instinct to create a spectrum of different styles, old and new, known and unknown, is the very essence of her as an artist and it takes place with every one of her concerts. She is the first pianist ever to play the First, Second and Third Piano Concertos of Nicolas Flagello, recording them with the National Symphony Orchestra of Ukraine and the Slovak Philharmonic, which were released to unanimous praise and chosen for one of the five "best of the year" recordings in 1996, 1999 and 2005, by Fanfare magazine. These premiere recordings were described as "splendid" and "superb." In his review (Classical Net, 2008), of the Naxos/Flagello Piano Concerto CD, Steve Schwartz writes:

Born in Belgrade, Serbia, Tatjana Rankovich has performed throughout the USA, Canada, Europe, Central and South America and as a guest soloist many orchestras worldwide. In 2002 and again in 2006, as a recipient of the Fulbright Grant and sponsored by the US State Department, Rankovich appeared in recitals throughout Serbia and Montenegro and as a Cultural Ambassador gave master classes at the Belgrade Conservatory. She is one of the main artists performing annually at the New York Contemporary Festival "Keys To The Future", where she received only lavish praise for her many premiere performances. In the summer of 2008, Tatjana Rankovich was a recipient of the prestigious State Award, "Golden Badge", which is awarded annually by the Serbian Ministry of Diaspora in Belgrade, Serbia.

Tatjana Rankovich has recorded several acclaimed discs for Phoenix USA, Naxos, Albany, Artek, Dezil, Citadel, and a highly praised 3-disk set of live recordings for IBOX. The review by Jerry Dubins of Fanfare Magazine (October, 2010) reads:
