I specifically asked about blogs, because I don't want just YouTube or Spotify channels, where there is only music (apart from the comments). I want some discussion too.
Mostly focused on the sound that was retrospectively called 'proto-punk' when it emerged in the US (MC5, Stooges, Patti Smith, etc) and Australia (especially Radio Birdman) and elsewhere just before punk.
But it's a sound that you can still hear in many bands today that were born long after that era. Especially in bands like The Hellacopters, etc.
RYM has solid music reviews, plus thorough rankings and excellent genre categorization :)
Sputnik is also pretty good, but not nearly as comprehensive: https://www.sputnikmusic.com/bestnewmusic
