La Concheperla is a traditional â€œmarineraâ€ initially transcribed by Rosa Mercedes Ayarza de Morales. This track is included in Felipe Albertoâ€™s Alma del Ayer album. Alma del Ayer is a collection of traditional Peruvian music recorded and produced independently in Saskatoon, Canada in the studio of Josh J. Palmer. All the songs were recorded with traditional instruments to maintain the authenticity of the criollo and Andean musical genres. Alma del Ayer is a work inspired by love for Peruvian music and the musical legacy of the Latin America.
