The Olympus Sound

The album was released in Ireland by 1969 Records and EMI on 19 August 2011. The iTunes version featured two bonus tracks not included on the CD. On its release, The Irish Times hailed it as "the best Irish album of the year to date"[4] while Hot Press said it was "the best thing [Pugwash] has ever done".[2] The Irish Daily Star named it among its top 10 Irish albums of 2011.[9] It was nominated for the Choice Music Prize 2011, an award given to the best Irish album of the year, in January 2012.[10]

After signing a three-year deal with British indie label Lojinx, The Olympus Sound was released outside Ireland on CD and vinyl on 16 April 2012. The CD version includes three bonus tracks not included on the original physical or iTunes releases.

The title of the album refers to the fact that Walsh recorded the initial demos for The Olympus Sound on an Olympus voice recorder and, instead of reworking them into more a polished form, was convinced by bandmate Tosh Flood to send them to him as they were. Flood then used the demos to record some instrumental parts, which ended up being used on the final version of the album.

I wanted to do what I normally do with a Pugwash record, which is wait until the second acoustic demo stage before playing the songs to people, but Tosh wanted to hear the Olympus dictaphone demos. I sent them over reluctantly, and within about three hours he'd sent back about eight tracks of guitars, keyboards and Mellotron on "There You Are", and those ended up being the ones we used on the final the song. It was the perfect sound so we kept it and started the album from there.
