"They take da' pain out, make it somethin' good, somethin' good. Wear yer' blues well, colt, you gonna earn every drop of em'. Yer' gonna be tangled up in blues," the old stallion told Blues, presenting him with the saxophone.

Blues himself tells us of his life after that day and as he explores what it means to be "painted blue"; to hope, to fear, to love, to lose. He tells us as he learns what really makes a stallion a stallion, what it's like to leave something you love behind, and what risks one must face in life or risk becoming nothing at all.

All of this, Blues tells us, takes place against the background of critical moments in his life and as he travels the scope of Equestria from Manehattan to Ponyville and Appleoosa. All the while the songs he learns from his pain mingle with the one his mentor, Moody Blues, revealed within him...something unbelievable the old pony did to bring it forth.
