Podger was born in England in May of 1968. Her primary education was at a Rudolf Steiner school in Germany, where she took up the violin early. In England, she studied at the Guildhall School of Music and Drama with Pauline Scott and David Takeno. At this point, the Baroque violin was still rarely taught in British conservatories. Podger, applying to study the instrument in her first year, was turned down because, she was told, the school's only Baroque violin had already been given to another student. Refusing to take no for an answer, Podger acquired a Baroque violin and secretly took lessons with Micaela Comberti at Guildhall. During this time, she also worked with her brother, Julian Podger, who had formed the Trinity Baroque ensemble in Cambridge. Eventually, Rachel was able to take regular classes on the Baroque violin, and she found a ready market for her talents as both a soloist and chamber music group leader.
One of Podger's earlier groups was the Palladium Ensemble, which had a distinctive sound with a viola da gamba, and one or more plucked instruments (no harpsichord) for a continuo. In 1991, she co-founded the successful Baroque group Florilegium, specializing in music from the 17th through 19th centuries. She also performed with the London Baroque, among other groups, during this time. In 1995, Podger made her recording debut, appearing with an ensemble of up-and-comers in an album featuring Purcell's Sonatas in three parts. The Palladium Ensemble was featured in a major rising-groups concert at the Concertgebouw in Amsterdam in 1996. In 1997, Podger became the leader of the well-established English Concert. In 1999, she made an ambitious solo recording debut, issuing Bach's complete sonatas and partitas for solo violin on two CDs; the albums appeared on the Channel Classics label, with which Podger has continued to be associated. She remained with the English Concert until 2002, after which she has often conducted Baroque groups from the violin. She became guest director of the Orchestra of the Age of Enlightenment in 2004, leading the group on a tour of the U.S. She would also become the guest director for other early music ensembles, including the Santa Fe Pro Musica and Musica Angelica. Podger often performed as a soloist with the Academy of Ancient Music, another long-established Baroque group. In 2007, Podger founded Brecon Baroque, specializing in the music of Bach and his contemporaries.
Podger also established an extensive teaching career, having taught at the Guildhall School as well as the Royal Welsh College of Music and Drama, the Hochschule für Künste in Bremen, and the Royal Danish Academy of Music in Copenhagen. In 2008, she became professor of Baroque violin at the Royal Academy of Music in London. The 2010s brought her prestigious honors, including the Royal Academy of Music/Kohn Foundation Bach Prize in 2015 and Gramophone Artist of the Year for 2018.
Podger's recorded repertory has extended as far forward as Mozart and Beethoven, but most of her recordings involve Baroque favorites. In 2018, she released a recording of Vivaldi's Four Seasons violin concertos with the ensemble Brecon Baroque, as well as a solo album: a transcription of Bach's solo cello sonatas for Baroque violin. In 2022, Podger returned with fortepianist Christopher Glynn, issuing an album of Beethoven violin sonatas. By that time, her recording catalog comprised some 40 items. ~ James Manheim, Rovi
