While revisiting the great blues bands of history we have to post a Butterfield clip. An authentic rendition of contemporary Chicago blues. This is of course the seminal Monterey festival - worth watching for its eye candy-like visual clarity even if you don't like the blues. There's some great Monterey footage on youtube - watch out for an alumni of 60s legends. Brian Jones was supposedly 'King' of the festival with Nico as his companion wandering serenely smiling among the crowd. Heady days.
