Having released more ambient-based/electronic recordings of the vibraphone under el fog, Masa became more interested in the sound of the vibraphone itself. He started to compose acoustic pieces and released the first solo album under his real name, titled Stories, in early 2013. Apologues sees Masayoshi for the first time use an array of instruments besides his lead instrument – such as the violin, cello, flute, clarinet, French horn, accordion, piano and snare drum played by friends, but arranged by Masa himself.

“My idea was to let those instruments express their own images or atmospheres that each instruments have by nature, or have been given in their history, and not treating them just as accompaniments of the vibraphone. Also, it was new for me to compose a song as a whole. As I wrote the vibraphone part first, I tried to hear other sounds in my head and tried to leave enough room for them and sometimes play only fundamental parts on the vibes.”
