Acquiring the Taste was the second album of English progressive rock band Gentle Giant, released in 1971.
This was a departure from the blues and soul styles found on their self titled debut. It was more experimental, more discordant, and with more varied instrumentation. In the sleeve text, the band made this famous declaration:
"...It is our goal to expand the frontiers of contemporary popular music at the risk of being very unpopular. We have recorded each composition with the one thought - that it should be unique, adventurous and fascinating. It has taken every shred of our combined musical and technical knowledge to achieve this. From the outset we have abandoned all preconceived thoughts of blatant commercialism. Instead we hope to give you something far more substantial and fulfilling. All you need to do is sit back, and acquire the taste."
The album cover has some innuendo in that it is made to look like a tongue licking an anus. However, when opened completely, it is actually a tongue licking a peach.(wikipedia.org)
