2009-01-21 · HQCD · 10 tracks · remastered reissue.
This is the PCCA.50027 remastered reissue of Miki Matsubara’s “Who are you?”, released on 2009-01-21 in HQCD format. The edition contains 10 ordered tracks. Its release date identifies this particular issue; the album itself belongs to 1980. Catalog number, medium and date together make this a more precise reference than the album title alone.
The sequence opens with “あいつのブラウンシューズ” and closes with “Twinkle Twinkle Starlight －三日月形の犬をもとめて－”. Those endpoints and the 10-position list provide a concrete way to check that a source describes PCCA.50027, rather than another issue carrying the same album name.
The source describes the edition as “2009 digital remaster”. These are release specifications, not a listening comparison or proof of identical masters on other formats. The linked album essay supplies the broader musical context.
