Brunnen is a solo project of Freek Kinkelaar of Beequeen. Two CDs worth of material have been released on Beta-lactam Ring: Swoon (originally released in 1993, plus some bonus tracks from an EP) and The Beekeeper's Dream (which features tracks recorded over 13 years). The songs are reminiscent of the quieter moments of Legendary Pink Dots or Psychic TV.
