Drawing Mello over albums I heavily associate him with Pt.1 (?)
Machines of Loving Grace - Concentration (1993)
The entire album’s industrial metal instrumental suits Mello very well. The electronic drums in particular reflect his canon theme songs in the anime. The themes of addiction, lust, and political apathy mixed with the described imagery of large cities, religion, and violence make it incredibly easy for me to picture Mello.
Personally, I associate the tracks “Butterfly Wings”, “Limiter”, and “If I Should Explode” with him the most, lyrically wise. They reflect my personal headcanons perfectly.
