Hi,
Too many people, in my book, have an issue with their music flowing and flying. That album has a lot of good things, that many people would not do today ... and would consider bad ... but emotionally, and experience-wise, that album is very nice and enjoyable to listen to ... and above all ... so simple! So simple!
It tells you that the amount of time on the studio, or at your DAW is not what it is all about ... it's about the music ... work it and make it better and let the players play and show up.
All too often, we waste time trying to perfect something ... that does not require perfectability, but we think it has to be better than what it is ... and when this perspective is missing, most music does not sound that good, or has any human qualities that we can associate with so much ... that we remember the darn album 42 years later!
