Okay, the user wants me to translate "performer-composers" into Japanese. Let me think about the correct term here. "Performer" is usually translated as "パフォーマー" or "演奏家" depending on the context. Since "performer-composers" refers to people who both perform and compose music, maybe "演奏家作曲家" would be accurate. But I should check if there's a more standard term. Sometimes, in Japanese, they might use "パフォーマー作曲家" but that might be less common. Alternatively, "演奏と作曲を行う人" could be a more descriptive translation. However, the user might prefer a concise term. Let me confirm: "演奏家作曲家" is the most straightforward and commonly used term for someone who is both a performer and a composer. I'll go with that.
