SECRETS won't keep when they tower six storeys above the heart of town in a riot of graffiti and boarded windows. The location of Where?House, the performance, dining, learning and socialising hub of Melbourne Music Week, was to be announced via social media on launch day, November 16.

Today, as curiosity grows and construction noise leaks from the corner of La Trobe and Elizabeth streets, we can reveal that the mystery venue will occupy two floors of the notoriously disused Argus Building.

The derelict 86-year-old monolith, under consideration for heritage listing but shamed by lord mayor Robert Doyle in July as one of the city's ''bomb sites'', will be transformed into a venue for bands, DJs, sound artists, film screenings, artist conversations, food and vintage clothing stalls from November 16 to 25.

The coup was orchestrated in collaboration with the City of Melbourne by event entrepreneurs Kevin Karlberg and Starr Guzman of Marksthespot, the production team behind last November's successful KUBIK installation in Birrarung Marr.
