What makes Comin' Thru by Quicksilver Messenger Service notable?

This album is notable for its exploration of themes related to incarceration and societal issues, particularly in tracks like 'California State Correctional Facility Blues.' It received a mixed critical response but helped solidify Quicksilver's presence in the evolving landscape of early '70s rock music, influencing contemporaries who were also addressing social issues in their lyrics. By the time 'Comin' Thru' was released in April 1972, Quicksilver Messenger Service had transitioned from their early psychedelic roots to a more blues-infused sound.
