As part of the Göteborg International Organ Academy 2012, Speerstra played the inaugural concert. The program consisted of keyboard music of Georg Böhm (1661-1733), including a number of pieces that are most often thought of as repertoire for large organ. The purpose of the concert was to explore examples from Böhm's keyboard output at the three most typical keyboard instruments that would have been found at home in Böhm's time: the harpsichord, clavichord and positive organ. The praeludium in g, which is often thought of as a plenum piece was performed at 16-foot pitch at the harpsichord in order to demonstrate what the opening section might sound like on a 16-foot North German harpsichord. These instruments were fairly common and very few of them have been preserved. A common modern copy of a two-manual french harpsicord can be used in order to play this piece at 16-foot pitch by tuning low F down to the D below, and tuning low G-sharp down to low F. The Bjurum organ was also used to present the chorale partita "Ach wie nichtig". The Bjurum organ, on permanent loan from the Skara länsmuseum is tuned in meantone with spit sharps and a short octave and comes originally probably from the 1640s from the important central German organ builder Nicolaus Manderscheidt. Böhm would certainly have known similar organs in his youth. The Capriccio in D and the partita on Freu dich sehr were performed on two clavichords that were presented as part of an exhibition of new instruments at the Academy.
