Bach’s Brandenburg Concerto No. 5 might be the most popular of the group among listeners, perhaps because its treatment of the harpsichord highlights the instrument as a virtuosic soloist in a quasi-concerto style. With the ensemble Baroklyn, Simone Dinnerstein performs this treasured work on the piano, along with other concertos and an arrangement of "Erbarm dich mein, o Herre Gott" for piano and strings.
