Here is an MP3 Audio clip by Singh Kaur which was recorded Live in the Los Angeles Gurdwara shortly before she passed away from ovarian cancer. I grew up listening to her wonderful music. Most of us used to sleep to her soothing tunes. They are a mixture of lyrics which are translation of Bani and various Gurbani mantras.
