The singer revealed that he wanted to record a new experimental album under a pseudonym, but the idea was rejected by his record label.
"They are not interested in testing these things out," Richard told Australian media, reports The Daily Telegraph.
"So the days of me going into the studio with a band and 12 new songs to create a whole new batch of magical four-minute tracks has passed.''
He added: "I often feel the rock and roll world has lost its attitude of fun. It should be fun to create music, it should be fun to go on tour.
"The industry has become too strait-laced for me. It's not adventurous. It's too safe.''
Cliff Richard previously told Digital Spy that he'd like to collaborate with Rihanna in the future.
