The Beatles are one of the greatest rock bands ever. The Beach Boys are one of the greatest rock bands ever. It only makes sense that Sir Paul McCartney would want to collaborate with one of the Beach Boys.
When Paul worked with the Beach Boys, things went down an unexpected path. Paul is a reknown multi-instrumentalist. The Beach Boys’ Brian Wilson asked him to play an uncommon instrument: celery.
The Beach Boys evolved from a doo-wop/pop band to one of the most experimental acts in the history of mainstream music. Some of their experiments included using non-instruments as instruments. Their album Pet Sounds famously features the sounds of dogs barking at some point.
