Musical artist who designed Reykjavik’s Imagine Peace Tower

As a detective working on this crossword clue, I first had to consider the key phrases present in the clue. The mention of Reykjavik caught my attention immediately as it is the capital of Iceland. The clue also mentioned the Imagine Peace Tower, which is a monument created by Yoko Ono, a well-known artist and musician. I tried to think of any other musical artists who double as visual artists that could have designed the tower, but none came to mind. Yoko Ono’s famous connection to John Lennon and her deep involvement in the peace movement also hinted towards her being the person alluded to in the clue. My final answer, ‘ONO‘, seemed to connect all the dots in the clue, and it became clear that Yoko Ono is the musical artist who designed Reykjavik’s Imagine Peace Tower, ultimately solving this crossword mystery.
