Some time ago I have discovered this duo from Japan that plays a nice selection of music with mandolin and ukulele.
For each video a special setup has been installed for the video, showing a special toy, a plant or like in the following video a drink:
Ukulele × Mandolin – MOLIENDO CAFE (コーヒールンバ)
Ukulele × Mandolin – 島人ぬ宝
BEGIN “Shimanchu nu Takara(=Treasure)” on the ukulele and mandolin.
Wish to keep our “treasures” on this islands eternally….
