At first you have to free him with help of the renovation master.
After that you can talk with him a couple of times after a run. Not everytime, but the most.
I think talking to Eurydice can lead you also forward to this achievement. Eurydice can be found as !-spawn in the second world (Asphodel). After many tries you will hear the music in the house of hades. Speak with him und leave the room. Achievement will pop.
