In November 2007, the Helsinki Chamber Choir elected Einojuhani Rautavaara and Kimmo Hakola as its first honorary members.  Both composers have had a close relationship with the choir.

As the Finnish Radio Chamber Choir, the choir recorded Rautavaara's complete a cappella choral works for
the Ondine label to international acclaim in the 1990s.  Kimmo Hakola was the Helsinki Chamber Choir's Artistic Director from 2005-2007 and the choir has premiered all of Hakola's choral works.
