Brazilian artist Lula Côrtes died on Saturday age 61 in Recife, Brazil, after a long battle with throat cancer.

Côrtes, whose full name was Luis Augusto Martins Côrtes, was best known for his album Paêbirú, released in 1975 and reissued in 2005. Paêbirú is a concept album about the four elements recorded with Zé Ramalho, and is now the stuff of crate digger’s dreams - a few hundred copies were printed, but most perished in what legend says was either a warehouse fire or river flood.

Côrtes also recorded Satwa (Brazil’s first private press LP) in 1973, formed art collective Abracadabra, and the short lived record label Solar, on which he released Paêbirú and an album by the collective Flaviola. Rosa De Sangue was released in 1980 as a bookend to the decade, around the time that his label, collective, and marriage were disintegrating. He said of Rosa de Sangue: “I want to close all of this with a golden key.” Côrtes then released O Gosto Novo Da Vida in 1981.

In 2008 he said to Now Again Records: “I think that the primordial objective of every artist is to make it so that his work speaks for itself, so that the person that exists within him transpires to come out so that we know him.”

More info on Côrtes is available at Time Lag Records and Now Again Records.

LA based artist Steve Roden is performing at London’s Cafe Oto on Wednesday, and at Cork's Strange Attractor event on 2 April. An exhibition of Roden’s work is also on at Susanne Vielmetter Los Angeles Projects in California until 23 April, titled Stone’s Throw.

The Cafe Oto performance will focus on Roden’s sound experiments - improvisatory performances using objects, field recordings and guitar pedals. The LA exhibition centres around a series of paintings and sculptures which started life as a collection of stones found in the studio of his grandmother after she died.

Roden says: “I’ve titled the show Stone’s Throw not only because of its reference to stones, but also because I like how the phrase is used to describe a short, yet inconsistent, distance from a source. The works in the exhibition exist in their finished forms a ‘stone’s throw’ away from the stones that fuelled their making... obviously, some remain a lot closer to their sources than others”

Ergo Phizmiz is attempting to crowdfund a production of Flann O’Brien’s The Third Policeman after having funding applications rejected. Phizmiz calls The Third Policeman a ‘neuropera’ - which he says stands for a “new experimental underground radical opera, and also stands for noisy eccentric uber-ropey opera, nasty exceptional uppity rabid opera, and naughty elegant umpty dumpty raging opera. That’s to say that it’s a home made opera produced and performed by thieves and vagabonds like myself.”

Sudden Infant (aka Joke Lanz) has cancelled a series of dates in Japan and Taiwan in the wake of the Japan earthquake. Lanz said on his blog: “After thoughtful consideration and consultation with my close friends in Japan and the Swiss and German embassies, I decided to cancel the whole Sudden Infant/Pain Infant tour including the one off show in Taipei and to postpone it for an indefinite period of time...I think with due respect for the victims and their relatives it is not appropriate to tour Japan right now in its worst crisis since 65 years."

Starting tonight on Radio 3, regular contributor to The Wire Ken Hollings is presenting Requiem For The Network, a series of five 15 minute shows which will run every evening this week. Hollings will be exploring the idea of the network in weaponry systems, commercial enterprises, banking and home entertainment: As these networks draw increasingly on the same operating platforms, the neutrality of the network is called into question.

The first show is “Welcome To The Labyrinth” which asks if “perhaps the hardest labyrinth to get out of is the one you don't even realise you are in?”

Hollings says: “Perhaps the most appropriate model for understanding the enduring nature of the network is the labyrinth: a structure of mystifying complexity where technology, deception and violence all meet. The US military, having been instrumental in developing the internet, has now withdrawn into its own secret labyrinth, which it considers a safe environment for the transmission of classified data.”

The rest of the week continues with “Victorian Search Engines”, “The Network Goes To War”, “I’ll Be Your Orange Juice”, and “Heads In The Clouds”. For more information head over to Radio 3 or Ken Hollings' blog.
