Answer
The answer is "Smash Your Head Against The Wall," which is the title of John Entwistle's first solo album, released in 1971 while he was still a member of The Who. The album showcased Entwistle's diverse musical talents, featuring a mix of hard rock, psychedelic, and blues influences. Despite receiving positive critical reception, it failed to achieve significant commercial success compared to The Who's albums during that period.
