Skilled with pen, baton or piano, Ian Arthur Plansker (b. 2003) is a versatile musician. He currently lives in Amsterdam where he is Artistic Director of the newly founded Orchestra Lagrandt and an accompanist at the Dutch Nationale Balletacademie.

Plansker is originally from Detroit, Michigan where he grew up in a musical household. He began as a flautist, studying under Sharon Sparrow before becoming interested in harpsichord under the guidance of Glenn Burdette. While in high school, he traveled to the Oberlin Conservatory where he began informal studies with Mark Edwards, Michael Lynn & David Breitman. His opera "The Spectres" was performed at the annual Oberlin Baroque Performance Institute when he was 15.

At 16, he moved to Montréal, Canada and enrolled at McGill University where he began to study harpsichord under the tutelage of Hank Knox and piano with Ilya Poletaev. While in Montréal, he founded the early music group Ensemble Bonaventure which went on to perform 3 years worth of successful concerts. Their inaugural performance was a fully staged production of Purcell's Dido & Æneas, which received an encouraging critique in Revue L'Opéra and led to an invitation to perform Rousseau's Le Devin du Village at the 2023 edition of the Festival Montréal Baroque.

While in his last year of studies at McGill, Plansker became increasingly interested in orchestral conducting at the encouragement of his mentors Elizaveta Miller and Dorian Bandy. He began to organize larger concerts with larger orchestras and choirs, championing Beethoven's Symphonies 5 & 7, Bizet's Jeux d'Enfants, excerpts from Mozart's Idomeneo & the North American Premiere of Thomas Linley Jr's Music for the Tempest with soprano Sophie Naubert. In 2024, he served as an assistant conductor for an Opéra McGill production of Massenet's Cendrillon under Stephen Hargreaves.

In August of 2024, Plansker moved to Amsterdam to begin studies with Olga Pashchenko at the Conservatorium. He has also taken up conducting studies with Arjan Tien and organ studies with Pieter van Dijk. In November of 2024 he was invited to conduct Mozart's concerto for three pianos with the Sweelinck Baroque Orchestra and soloists Izaac Masters, Matias Gomez Saenz Gimeno & Mariam Chincharauli. Alongside several classmates, he has founded Orchestra Lagrandt, a period performance ensemble with a specialization in 19th and early 20th century repertoire. They gave their first concert on March 1st at 7 P.M. with the "Great" C major Symphony of Franz Schubert alongside a string serenade composed and conducted by Plansker.
