The story goes that it was Leonard Cohen’s son Adam who pressed his father for a back-to-basics album, one where the most magnificent mutter in rock could operate unhindered by Cohen Sr’s taste for flamenco guitar and synths. We may have something as banal as pester power to thank, then, for this exquisite 14th album from the Montreal poet, held by recent Nobel laureate Bob Dylan – gnomic as ever – to be “No 1” to his “zero”.
Can you help me with understanding the passage in bold which I am not able to fully understand. I am not sure to which part of the text the bolded passage is related. What does the author of the review want to say? Does it mean that Bob Dylan expressed the thank for new Lenonard Cohen's album?
