Söndag 11 april 2010 framförde San Francisco Symphony Chorus under ledning av Ragnar Bohlin ett nytt verk av Fredrik Sixten: "Let there be" för kör och slagverk. Joshua Kosman, San Francisco Chronicle Music Critic, skriver i sin recension:
"...Sixten's "Let There Be," an eight-minute plea for universal brotherhood scored for chorus and percussion, opened the concert in a ripe and inviting account. The piece is saddled with a thin, sanctimonious text by poet Maria Küchen, but Sixten's music - stirring and broad-beamed without seeming pompous - carries the day.
Particularly impressive is the way the accompaniment, with timpani predominating, establishes a harmonic foundation above which the choral melodies curl and soar eloquently..."
