Mendy Portnoy

Mendy Portnoy is an English-born Israeli singer, pianist, composer, and producer. He is best known as half of the folk rock duo the Portnoy Brothers with his older brother Sruli. He has also released three albums as a solo artist.

Early life Portnoy was born in Manchester, England, the seventh of nine children. His father is a rabbi and former orchestra conductor. He and six other siblings made aliyah to Israel as adults, however Portnoy and his brother Sruli have since moved to the USA where they currently reside (as of 2024).

Portnoy studied music from a young age and began playing together with Sruli around age 14. He originally took guitar lessons, with Sruli taking piano, before the two switched.

Career In 2010, he performed at the Complete Unity Concert at Heichal Shlomo alongside Aharit Hayamim, Shtar, and JudaBlue. He and Sruli participated in the music video "Waving Flags", performed by campers and volunteer staff at Camp Simcha.

Mendy Portnoy was featured on composer Yossi Green's 2015 album Pianesque. That same year, he collaborated with singer and saxophonist Daniel Zamir on Esa Einai, an album of Shlomo Carlebach songs, and released a short online-only piano album entitled Holy Days.

He was the final keyboardist for the Jewish rock band Hamakor, performing on their 2014 single "Lift Me Up".

As of 2020, Portnoy moved to New Jersey to work for Jewish grassroots movement and music company Thank You Hashem where he works as a music producer. Portnoy became involved as a producer after Moshe Storch, a musician recording a song with TYH at that time, approached him to produce a song for TYH whilst Portnoy was visiting New York. His arrangement of Shomati/Take Us Home impressed the TYH executives, who had "been struggling to get [that particular] niggun out there". They ultimately decided they wanted Portnoy to run their studio—even though they had yet to build one. He became an integral part of the production team, contributing to every track on the album and has continued in his role ever since.
