From Genesis to Revelation vs Chicago Transit Auth

Both albums are great.  This is not really an easy choice for me.  CTA's debut album was not their best,  but possibly their second best album and  I think From Genesis to Revelation is a vastly underrated album,   one of the best concept albums of 69, and  is one of the Genesis albums I enjoy listening to the most.     Of course both groups changed dramatically from their earliest  incarnations, and Genesis's change may have been a bit more dramatic.  I will say that if Genesis had maintained the Moody Blues like style that they were embarking on in 69  and never became known as a progressive icon, we would be looking back at From Genesis to Revelation as a classic, not as group "stumbling for an indentity".      That being said, I still have to give a slight edge to CTA's debut album which has a soulfulness that transports me back to the 60's every time I listen to it.
