Joplin, Janis - Pearl - MFSL Test Press

Vinyl Record, Used - Joplin, Janis - Pearl - MFSL Test Press

Mobile Fidelity Sound Lab, the JANIS JOPLIN album titled PEARL, TEST PRESSING

Never released.  This is not the current 2 disc version that is available. 

MFSL 1-154 was mastered and pressed for consideration, and then never put out into the marketplace, thus remaining of the most desirable Mo-Fi titles ever seen or heard about.
