Excerpt from Back to Schoolin'

Presence is an album written and recorded under difficult circumstances in late 1975 shortly after Robert Plant suffers a severe automobile accident and is confined to a wheel chair, effectively ending any touring plans for over a year. The album reflects the tension and desperation of the time, and is therefore an aggressive all-electric affair. Note also that all the music is composed by Page (with the lone exception of “Royal Orleans” which is a group composition), resulting in the first Zeppelin album completely devoid of keyboards.
