I accept that the top-linked page is just thumbnails, but the underlying reviews are no better.
No doubt, this is a feature of Bandcamp's editorial preferences. I'm sure that Mr Sumner could write better reviews than the original reviews. I would not presume to judge a writer by the copy that he or she generates for a platform like Bandcamp, which is essentially a corporate copyrighting job, no different to "Top 5 Best Footbaths in Yekaterinburg". I certainly don't expect Mr Sumner to appear here and start to slag off Bandcamp's editorial process. Overall, I appreciate anyone bringing records to my attention, and I like the fact that these are a different set to those that have appeared on other lists.
But whatever the case may be, it is not true at all that it is rare to encounter a good album review or that criticism of these particular album reviews reflects the impossibility of pleasing everyone.
