Petros Spatharos / Datalogs

You step off the street and the bass finds you before your eyes adjust. The room is dim, compact, and already warm — a handful of people have claimed positions near the speakers, drinks in hand, bodies angled toward the DJ booth. Outside, the tables are half-full with people who drift between conversation and the music leaking through the door.

Petros Spatharos brings his particular strain of dark, restrained electronic music to B side Athens alongside Datalogs. Spatharos is an Athens-based producer whose output spans industrial textures, atmospheric techno, and EBM — his debut album Spacetime Adventures landed on Body Musick in 2021, seven tracks moving from downtempo electronica to atmospheric industrial. A split release with Filmmaker on Dalmata Daniel followed in 2023, and his Vultures EP dropped on the FERMA label in late 2024, with tracks like Datura and Xorkia showcasing what one reviewer described as underworld techno with an extremely restrained tempo. His sound is clean rather than chaotic — slow-building, bass-heavy, and calibrated for rooms exactly this size. Datalogs, also active in the Athens electronic circuit, shares the bill and the night's trajectory.

The crowd at B side gravitates toward the underground end of the electronic spectrum. You will find regulars who track Athens label releases, visiting DJs who come here on off-nights, and people who wandered in from Omonia's surrounding streets because the music pulled them to the doorway. The dress code is whatever you were already wearing.

| Aspect | Details | |--------|---------| | **Setting** | B side Athens, Mavrokordatou 6, near Omonia — compact bar with inside dance floor and outdoor seating | | **Vibe** | Underground, unpretentious, bass-forward — a locals' club that does not advertise | | **Sound** | Industrial-leaning techno, EBM, dark electronics — room-scale system, felt as much as heard | | **Door** | Walk-in, no guest list |

The night builds in the way that small-room electronic sets build: the early hours belong to the bar and the outdoor tables, the music pulling at a lower BPM. As the room fills, Spatharos and Datalogs can push the sound darker and heavier, feeding off the density. By the later hours, the inside floor is the center of gravity — people who came for the music find each other, and the room contracts around whoever is playing.

If you want a large-scale club night with light shows and bottle service, B side operates in a different register entirely — this is a bar that happens to have a sound system and a booking policy. But if you want to hear Athens-based producers play dark electronic music in a room small enough to feel the bass in your ribcage, on a Saturday night where the entry price is the cost of your first drink, this is the room.

B side sits at Mavrokordatou 6, a short walk from Omonia metro. The bar opens in the evening and runs late, with DJ sets typically building through the night. Cocktails are well-made and affordable, beers cheaper still. The outdoor area lets you step away from the volume without leaving the premises — useful when you need a break from the sub-bass. The neighborhood around Omonia has its own energy after dark; walk with awareness, as you would anywhere in a city center.

No flyer, no Instagram countdown, no presale link. Spatharos and Datalogs playing a room where the sound system does the talking and the walls do the rest.
