PLaying Am blues and working in dorian and mixolydian modes into it, diffirent licks and general improv. It works ofc but i dont really understand the relationship between the penta and the modes used.
Anyone that can share useful articles that i havent stumbled across yet etc?

You could click on the thread on the stickies about modes, and read the two threads linked there. That should help you with understanding those.

About why it sounds good to mix dorian and mixolydian with a minor scale, my guess is that you're not playing anything related to modes, but just a minor scale with some borrowed tones. In this approach it boils down to creating and resolving tension. I really can't recall specific articles about it though.

Take a look at scale construction.

You mentioned the modes so I'm going to talk about them.

Am pentatonic is A C D E G
A dorian is A B C D E F# G
A mixolydian is A B C# D E F# G

As you may see, they share a lot of notes. A mixo and A dorian are just one note different (C# in mixo, C in dorian). A dorian has the same notes as Am pentatonic + B and F#.

You are actually just mixing major and minor. That's really common in blues.

But yeah, this is how I understand the relationships between different scales. Let's have A as our root note.

A phrygian - A Bb C D E F G (think as minor scale with a minor 2nd)
A minor - A B C D E F G
A dorian - A B C D E F# G (think as minor scale with a major 6nd)
A mixolydian - A B C# D E F# G (think as major scale with a minor 7th)
A major - A B C# D E F# G#
A lydian - A B C# D# E F# G# (think as major scale with an augmented 4th)

Also notice how A phrygian, minor and dorian all have the same notes as Am pentatonic and A mixo, major and lydian all have the same notes as A major pentatonic. The notes of the minor pentatonic are underlined (in the minor modes) and the notes of the major pentatonic are bold (in the major modes).

Now try playing all the different scales and pay attention to the difference in sound.

Oh, and here's tab if it helps:

A phrygian:

e|-------------------
B|-------------------
G|-------------0-2---
D|-------0-2-3-------
A|-0-1-3-------------
E|-------------------

A minor:

e|-------------------
B|-------------------
G|-------------0-2---
D|-------0-2-3-------
A|-0-2-3-------------
E|-------------------

A dorian:

e|-------------------
B|-------------------
G|-------------0-2---
D|-------0-2-4-------
A|-0-2-3-------------
E|-------------------

A mixolydian:

e|-------------------
B|-------------------
G|-------------0-2---
D|-------0-2-4-------
A|-0-2-4-------------
E|-------------------

A major:

e|-------------------
B|-------------------
G|-------------1-2---
D|-------0-2-4-------
A|-0-2-4-------------
E|-------------------

A lydian:

e|-------------------
B|-------------------
G|-------------1-2---
D|-------1-2-4-------
A|-0-2-4-------------
E|-------------------


The positions are of course movable and work with any root note.
