Ryan reunites with his oldest sons, Kirtland and Logan, building on their Sing the Sorrow deep dive to unpack AFI's ambitious 2006 follow-up Decemberunderground, the platinum-selling juggernaut that catapulted the band to Billboard number one with its gothic-punk evolution. Produced once again by Jerry Finn, the album's sprawling soundscape—blending post-hardcore fury, synthwave shimmer, and emo introspection—features explosive singles like "Miss Murder" and "Love Like Winter," sparking lively debates on Davey Havok's haunting vocals, Jade Puget's atmospheric riffs, and themes of isolation in tracks like "The Interview" and "Endlessly, She Said." The trio swaps stories of blasting the record during road trips, geeking out over hidden bonuses like the INXS cover "Don't Change," and tracing AFI's shift from Warped Tour moshers to arena-ready icons, all while laughing about how the album's "eerie Cure-like" vibes soundtracked their punk awakenings and strengthened their father-son bond.
