Rating metrics:
Outliers can be removed when calculating a mean average to dampen the effects of ratings outside the normal distribution. This figure is provided as the trimmed mean. A high standard deviation can be legitimate, but can sometimes indicate 'gaming' is occurring. Consider a simplified example* of an item receiving ratings of 100, 50, & 0. The mean average rating would be 50. However, ratings of 55, 50 & 45 could also result in the same average. The second average might be more trusted because there is more consensus around a particular rating (a lower deviation).
(*In practice, some albums can have several thousand ratings)
This album is rated in the top 16% of all albums on BestEverAlbums.com. This album has a Bayesian average rating of 74.0/100, a mean average of 72.6/100, and a trimmed mean (excluding outliers) of 74.5/100. The standard deviation for this album is 20.6.

Shame that the limits of vinyl meant there is a fade in/out between each of the 2 performances. It does diminish the natural progress of the music. Recording quality really poor, no better on CD than the original vinyl. Still def. worth buying

I want to like this more, but not enough dynamic, and it's to busy to get lost in it like a drone (for me).
