Suicide were very 50s influenced in the vocals and to an extent some of the lyrics. Frankie Teardrop is my favourite on the first album. Very influential band and bizzarely, Springsteen covers 'Dream Baby Dream' really well. This Heat are generally classified as post-punk (isn't every bloody thing). Recorded in a disused cold storage facility, very DIY, very good. TG were going as COUM transmissions from the late 60s making 'art' statements influenced initially by Dada then later the Vienna Actionists. They were called 'Wreckers of Civilisation' in parliament during an exhibition at the ICA and went more music based. DNA (and to a lesser extent Swans) were part of the late 70s New York 'No Wave' movement. Swans took it further than most with a 'F U' attitude and explorations of the lowest humanity could stoop to. They then became a bit more tuneful whilst railing against religion and cults (Children of God, The Burning World), finished with some classics (Love of Life, White Light...., Great Annihilator) then declared themselves dead. Then Michael Gira got itchy and has released four brilliant and ever longer albums (this year was 'The Glowing Man') bit of a Swans obsessive myself.
