Heather Miller Lardin enjoys a diverse career performing and teaching on historical and modern double basses and viola da gamba. She appears regularly with Tempesta di Mare, Philadelphia Bach Collegium, and Brandywine Baroque. Other recent engagements have brought Heather to perform with the Staunton Music Festival, Handel & Haydn Society, and the Dryden Ensemble. Lardin is founding director of Night Music, which performs chamber music of the Revolutionary and Romantic eras on period instruments.

Lardin directs the Temple University Early Music Ensemble, which includes viol and recorder consorts, voices, lutes, and Baroque ensembles; she also directs the Amherst Early Music Winter Weekend Workshop held each January in Old City Philadelphia and Camden. In summer 2016 she taught a week-long historical double bass course at the Amherst Baroque Academy and served as faculty at the Curtis Young Artists Summer Program. Lardin maintains a select private studio for Suzuki and traditional double bass students. A recipient of a Viola da Gamba Society of America Consort Loan grant, she also offers viol consort classes for children ages 5-9.

Lardin is the editor of the early bass feature "Rumblings" in Bass World, the journal of the International Society of Bassists (ISB) and regularly presents recitals and lectures at ISB conventions. From 2006 to 2013 Lardin was Artistic Director of NYS Baroque (Ithaca, NY). Under her direction, the ensemble appeared at the Skaneateles Festival and developed an arts immersion program in which Ithaca High School students explored European culture through literature, music, dance, theater, gesture, and costume.
