What struck me about Pearl upon listening to it again recently, is the authenticity of the music. Some reviewer once claimed that rock merely gets stale whereas pop music rots with time. There is nothing stale about Joplin and her band on this all-time classic. After all these years, it remains a magnificent listening experience because of the quality of the songs, the band's tight playing and the impressive emotional range of Joplin's vocals. Unlike on Cheap Thrills, where there was mostly a cosmic battle between her voice and Big Brother's heavy metal onslaught, here the voice is the star. My favourites on an album of classics include the incredible Me and Bobby McGee, the tender A Woman Left Lonely, the nervous Half Moon, the emotional Cry Baby, the buoyant Get It While You Can and the plaintive/humorous Mercedes Benz. Perfect arrangements, brilliant playing and masterly vocalization combine here to create a timeless masterpiece.
