Huber was born in Straubing, in Bavaria, in 1969. He attended the Hochschule für Musik und Theater in Munich, studying piano and vocal accompaniment. In his coursework for the latter, he attended a master class with the great baritone Dietrich Fischer-Dieskau. Another member of the class was Gerhaher, and from that meeting stemmed a long collaboration. Huber has also accompanied various other top-flight singers, including mezzo-soprano Bernarda Fink, soprano Diana Damrau, and soprano Ruth Ziesak. He is also a member of a multi-artist song-performance group called Liedertafel, and he has played chamber music with the Artemis Quartet. As a solo pianist, he has given recitals in Munich and Regensburg, and abroad in France and New Zealand. Huber also accompanies a variety of singers at German festivals, including the Rheingau Music Festival, the Schubertiade Schwarzenberg, and the Schwetzingen Festival. In the U.S., he has appeared as an accompanist at Lincoln Center and Carnegie Hall in New York.
Huber has won several major awards, not only in collaboration with Gerhaher (the pair won an Echo Klassik award in 2002 for their recording of Schubert's Die Winterreise, D. 911, and a Gramophone Award in the UK in 2006 for their album Abendbilder), but also as a solo player; he was a prizewinner at the Internationaler Klavierwettbewerb Johann Sebastian Bach Saarbrücken in 2001. Huber's discography, mostly with Gerhaher and other singers, is large. In 2017, he and Gerhaher released a recording of the rare Brahms spoken-musical work Die schöne Magelone; the pair also toured with the work to Munich, Heidelberg, and London. In 2019, he backed Constance Heller in an album of songs by composer Hans Sommer. ~ James Manheim, Rovi
