Alright, this last LB chapter is probably the closest I’ve found to a precursor to Lindsey Buckingham’s later 70’s sound. It makes sense too since after the Cowsills broke up Lindsey was in a band with them for a short bit in the early seventies. ‘Nervous Breakthrough’ came out in 1971, two years after Bill Cowsill was found smoking weed by his dad and got kicked out of the band. The last installment of Buckingham influenced (promise):
Bill Cowsill – When Everybody’s Here 
Somewhere between Sticky Fingers and Buckingham. Pretty unfortunate that after releasing his only solo album he basically disappeared into a drug haze for the entire decade after its release.
