They are actually Ashkenazi. Breslov Chassidim, to be specific. Large, chrocheted yarmulkes with tassels (usually black or white) + long peyos + dancing and singing = Breslovers. You will notice on the yarmulkes appear the phrase נ נח נחמ נחמן מאומן or 'Na Nach Nachmah Nachman me'Uman', a permutation of the name of Rebbe Nachman of Breslov zatza"l who is buried in Uman, Ukraine, a place of pilgrimage for Breslov Chassidim on Rosh Hashanah.
