Letur-Lefr (pronunciation: /'lɛtɹ̩ 'lɛfɹ̩/) is an EP by John Frusciante, released on July 17, 2012 on Record Collection. It was released in multiple formats including 32-bit digital download and cassette. The EP features Frusciante singing, playing all the instruments and engineering, as well as his wife performing backing vocals and a "few friends on vocals, mostly MC'ing".
Frusciante said of this album and its follow-up, PBX Funicular Intaglio Zone, "I consider my music to be Progressive Synth Pop, which says nothing about what it sounds like, but does describe my basic approach. I combine aspects of many styles of music and create my own musical forms by way of electronic instruments. The tracks on Letur-Lefr were recorded in 2010 and PBX was recorded in 2011. Letur is a compilation, a selected portion of music I made that year while PBX was conceived as an album, the songs having been recorded in succession. The records are very different from each other."
