I've used and subscribed to Allmusic for many years and have read, agreed, disagreed, recommended this site to others, and learned so much. I have wide, eclectic tastes that the site usually covers, but, the progressive bluegrass coverage is barely minimal. The most recent and major example is Billy Strings. Not a single bit of music has been reviewed, induing the new album that dropped yesterday, 9/24/21. This young man is a major talent and is pushing genres and boundries hard and is going to be a major, major player.
Hope you listen in and enjoy!
