The band.

The musicians.

Rob Curto (composer/songwriter, piano and diatonic accordions) is a musician with a reputation for dizzying skill and deft mastery of the accordion across musical and geographical boundaries. Most recently, he spent the better part of the last decade touring extensively with his band Matuto, known for its distinctive “Brazilian-bluegrass” sound. Mixing the roots Americana stylings of the great Bill Monroe with rhythmic and melodic elements from Brazil, Curto has been part of a movement to establish the accordion as a versatile and important instrument in contemporary roots music.

In addition to the Brazilian music for which he has become well known, Curto has gained a reputation as an all-around master of the accordion and has been in high demand across genres. His musical collaborations include performing and recording with Latin Grammy award winner Lila Downs; Klezmer clarinetist David Krakauer; trumpeter/composer Frank London; Punjabi Indian singer Kiran Ahluwalia; and icon of Brazilian Forró, the great accordionist Dominguinhos. Curto is also an enthusiast of Irish button accordion and studies with acclaimed B/C box player and NEA National Heritage Fellow, Billy McComisky.

Curto has toured internationally including across Europe, Asia, and Africa, and has represented the United States State Department abroad. He has been a staple at festivals like Wintergrass, Red Wing Roots, and Rhythm and Roots, and made his Philadelphia Folk Festival debut with his band Forró for All in 2018.
