The Muggiati-Feldman brothers come from a family of long musical traditions. From their mother Anna Muggiati, niece of Roberto Muggiati,  a well known Brazil's jazz critic. From their father Daniel Feldman, brother of David Feldman, "one of the great talents in today's Brazilian instrumental music" on the piano, and son of Myrna Herzog, an internationally known viola da gamba performer, conductor and researcher, and of Eliahu Feldman, one of the first baroque violin players in Brazil; and great-grandson of Nikolaus Schaack, a zither player and “a pioneer of the technique of the zither and of the composition for this instrument (MGG Dictionary)”.  

The Muggiati-Feldman household has been the stage for frequent jam sessions since 2010. During the first jam sessions, then 6 and 4, the brothers had to be bathed and put to bed for their parents to continue playing.  On the most recent ones, they led the musicians, old and young, into playing everything from Bossa Nova, through Blues, Hard Bop, Bebop, Ballads, and Avant-Garde Jazz. Based in New York, NY, the Feldman brothers can be often found at Smalls' jam sessions.  While living in San José, California, it has been possible to listen to the Muggiati-Feldman brothers in some of the South Bay and Peninsula's most popular Jazz joints, including Art Boutiki, Café Stritch, 7 Mile House, Little Lou's BBQ, and Savannah Channel Winery, either in jam sessions or as guest artists. Since moving to NYC in December 2021, they can be heard at jam sessions at Patrick's Place and Smalls or performing with bands at venues such as Birdland and Jazz at Lincoln Center.
