have i used commas correctly in this sentence?

Ark, not sure since it's incomplete. Maybe "It was my boy, Eric Prydz, bending minds." Actually there's a trend away from the comma where meaning is clear so you don't really need either one, depending on context and mood

I've no idea what your intent is here...but it is neither clear, grammatical nor is it a sentence.

it's a caption for a picture of a show. my boy Eric Prydz bending minds at epic 4.0
