I'd like to incorporate a texture similar to this album cover for a project I'm working on. Any suggestions of good starting points/tutorials to check out? I'm used to using photoshop, illustrator, sketch and photography so anything incorporating those tools is best.
That looks pretty simple.
I would just make some lines of color and use the liquify tool or some smudge one. You can try adding a mask to achive defined edges.
Try not to put complementary colors together or you will have a grayish image.
Work on RGB mode.
If you want a totally editable aproach take a look at mesh fills: https://helpx.adobe.com/illustrator/using/meshes.html
