Ah yea, I didn't read your post properly, thought you were listing what 'messed with' qualities you heard.
From an entirely theoretical perspective, a minor blues would be likely to include Cm7, Fm7, G7, Ab7 and/or Dm7b5, and as said any chords would be likely to be messed with.
A few common variations are Db7 (tritone substitution for G7), sharp or flat 9 on the Dom7 chords (especially the G7), Abdim7 (effectively G7b9 with the root omitted). In jazzier blues, the 'non altered' Dom7 chords will likely be 13ths and maj7/m7 chords will likely have a 9 in. Also something I've heard in minor blues is the III chord, leading to a #IIIdim7 (III with raised root) going to the iv (so in C: Eb, Edim7, Fm7).
This is all theory though, I didn't look for each example in the recording.
