There is complexity in simplicity, and Sparrow Nights is Peter Brötzmann and Heather Leigh's most enduring record to date, and their first studio album. A series of emotionally rich and boldly elucidated tonal and timbral exchanges played like compositions on pedal steel and reeds, the tracks (released as a 6 track LP and 10 track CD) are cold-forged minimalist blues motifs dragged from instrumental laments.
