Polish classical pianist Krystian Zimerman and the Vienna Philharmonic pay tribute to the spirit and passion of renowned 20th-century composer and conductor Leonard Bernstein with these 1991 performances of Beethoven's Piano Concertos nos. 1 and 2. Although released to the public several years after Piano Concerto no. 1, Piano Concerto no. 2 was actually composed by the master almost 10 years earlier.
