Johan Brouwer has made various CDs, including a CD with his collection of harpsichords, built by David Rubio, a CD with radio recordings from '73 and '83 made by the NCRV on the Hinsz organs of Midwolda and Appingedam and 2 CDs in the book ‘35 Years of Collegium Musicum Groningen', in which he can be heard as continuo player and conductor. 2012 saw the release of a CD in which works are played on the famous Arp Schnitger positiv (1695) in Nieuw-Scheemda and on his Italian harpsichord, built by David Rubio (1977) after Giovanni Giusti (1679).
