Another track that sticks out for its disquieting string arrangement is ‘Friends’ off Led Zeppelin III. By 1970 had no shortage of pomp. Having returned from an exhausting tour of the US, the band retreated to Bron-Yr-Aur, a small cottage in the Dyfi Valley. Hats off to John Paul Jones. The bass player took the tranquility of their setting and created a string arrangement that would open a creative door – a precursor to ‘Kashmir’.
