Bach Concerto in D Minor
This Largo ma non tanto movement of the concerto was selected by Douglas Yeo and Gerry Pagano for their album Fratres. After hearing it prior to recording it, Michael suggested that it would benefit from some strings and a harpsichord sound from that period. Doug and Gerry agreed so Michael arranged the accompaniment.
This arrangement download comes with the two bass trombone parts as well as those two parts up an octave for two tenor trombone if so desired. The audio track of the strings and harpsichord are included as well.
Here is recording of Isaac Stern and Itzhak Perlman performing the movement with the New York Philharmonic. Notice that they play it significantly slower, but the faster tempo makes it easier on the trombones.
