Who We Are

The Madoc Quartet: four accomplished string players with  a passion for chamber music and the desire to share that passion with contemporary audiences. MQ's debut concert series, "The All Terrain Tour 2020," sponsored by the Quinte Society for Chamber Music, was an unmitigated success, earning accolades for excellence in performance and a warm, inviting presentation style. Committed to finessing the traditional string quartet repertoire and exploring new music by modern composers, recent performances include the premiere of a new work by  Canadian Jacques Marchand scored specifically for this ensemble. MQ  leader Sebastian Sallans says, "Canadian composers are writing the music for our time. The String Quartet is a sonorous, versatile and stunningly beautiful instrument for which the great composers wrote their best music. We want everyone to be able to hear and enjoy chamber music at its best.” Exciting performances can be expected from this ensemble of exceptional musicians.
