Alexander Weimann is one of the most sought-after ensemble directors, soloists, and chamber music partners of his generation. He has traveled the world as a member of the ensemble Tragicomedia; as a frequent guest of ensembles such as Les Boréades, Cantus Cölln, Freiburger Barockorchester, Tafelmusik, and the Gesualdo Consort; and as musical director of Les Voix Baroques and Le Nouvel Opéra.

Weimann made his North American recording debut with the ensemble Tragicomedia on the CD Capritio (Harmonia Mundi USA), and won worldwide acclaim from both the public and critics for his 2001 release of Handel's Gloria (Atma Classique).

Volume 1 of his recordings of the complete keyboard works by Alessandro Scarlatti appeared in May 2005, and was nominated for an Opus prize as the best Canadian early-music recording. Volumes 2 and 3 of the complete Scarlatti works will be released shortly. In 2007, his recording of Buxtehude's Membra Jesu with the Montreal-based ensemble Les Voix Baroques won an Opus prize, and was nominated for a Juno Classic Award

Weimann was born in 1965 in Munich, where he studied the organ, church music, musicology (his M.A. thesis was on Bach's recitatives), theatre, medieval Latin, and jazz piano. For several years, he has taught early music performance practice to voice and instrumental students at the Université de Montréal. Singers of note, such as those with the Atélier Lyrique Montréal and other opera studios, seek his services as a vocal coach.

Recently, Alexander Weimann has returned to jazz; he has played piano on several CDs, and in a video clip for CBC Showcase. After some years in Berlin, he now spends as much time as possible with his family in his adopted home, Montreal, and is active in both his kitchen and his garden.
