Two-CD set (including discussion disc) includes the rarely recorded Lieder eines fahrenden Gesellen (Songs of a Wayfarer). Conductor Benjamin Zander, who has built a distinguished body of work on Telarc with acclaimed recordings of Mahler symphonies, adds yet another chapter to this oeuvre with a brilliant recording of Mahler’s Symphony No. 1 in D Major. Dividing his time between conducting and teaching (his class on interpretation at the New England Conservatory attracts students from all over the world), Mr. Zander travels extensively, giving master classes, touring with the Conservatory’s Youth Philharmonic Orchestra, and conducting guest performances.
