London After Midnight (LAM) was formed in the 1990s by Sean Brennan. Unlike most music projects, LAM has retained and nurtured the progressive political and socially aware element of the later punk scene that virtually vanished from the music scene in the early 90s, and has developed as a deep, passionate and political dark rock music entity. Live members vary. LAM has gained a large and loyal following all over the world, from the USA, Europe, Latin America (where LAM has toured extensively), and beyond, to Russia, Japan, China and elsewhere (appearing in major press and securing distribution deals with record labels).

London After Midnight has headlined and co-headlined concerts and major festivals with bands like Blondie, Morissey, Bauhaus, The Cure, Green Day, HIM (HIM has cited LAM as a favorite artist), and countless other major artists. LAM has performed to crowds of over 30,000 people as headliner or co-headliner on major music festivals around the world. Still, London After Midnight maintains a strong underground and independent "personality" despite being a top seller (charting in the top 10 and top 20 of the European DAC and alternative charts with each album released) and a major draw at music festivals year after year.

Songwriter, instrumentalist, producer and founder Sean Brennan is known for his strong stances in favor of animal rights, pro-environmental and human rights issues, and progressive/liberal politics. Whatever the approach or subject matter, the music of London After Midnight is deeply touching, powerful, socially aware, romantic, emotional, haunting, moving, and even exhibits a morbid wit with its sarcasm and sardonic humor (listen to the tongue-in-cheek "Your Best Nightmare" and try not to think of an Edward Gorey story).

LAM is all this, having a very well defined personality while at the same time appealing to a wide variety of people. There really is no classification that fits London After Midnight (despite LAM's "dark" image) because the music is so varied and the lyrical content (and even LAM's personality and causes) are uncommon in todays music scene, often breaking boundaries - much to the outrage of people who live and die by genre labels. Sean Brennan shuns all labels (as any artist worth their salt will do) and the music he creates can really only be classified as "London After Midnight".
