Weber grew up in a Pupa Hasidic sect family in New York City. He began singing at the age 9 although his career did not start until the release of his first album in 2007. In later life he has moved away from Pupa and now identifies with Breslov. As a Breslov he travels to Uman on Rosh Hashanah and performs, often in front of thousands of people. In 2016 he released the album Aguda Achat which was well acclaimed by critics, with Yeshiva World News saying; “The album ranks top in quality and above standard. What sets Agudah Achas apart is the dedication and attention that Beri devoted to every note, composition and even the artwork to ensure that this masterpiece, Agudah Achas, denotes his true essence and talent.”  In 2017 he produced a music video of the song ‘Rabi Shimon’ from the album Aguda Achas in honor of Rabi Shimon bar Yochai and the festival of Lag B’Omer, which became a major hit. Later in the same year he released a single “Vtaher Libeiunu” in advance of the festivals of Rosh Hashanah and Yom Kippur. Weber’s 2018 single ‘Kerestir’ also went with the Kerestir Challenge, this called for people to film themselves performing a section of the tune. This was very popular, and was described by Matzav as “going viral”.
