我們的電影，是音樂。只有音樂，沒有別的了。出道12年來第一部音樂電影休團3年前的完美呈現這次收錄成《故事未了》音樂專輯的13首歌曲，是蘇打綠的第四張live專輯，在即將休團三年之際發行，期盼為他們的音樂作品劃下完美的句點。關於蘇打綠的音樂電影《故事未了》蘇打綠的電影不像既定印象中的電影，它的主角是音樂，只有音樂 ，沒有別的了。每一首歌有一幕場景，每一句歌詞就是一串對白，《故事未了》其實不過是一首歌緊接著下一首歌，而歌與歌之間的流動，承載起每一個小小的故事；這些故事遇見你，是我們的劇情。蘇打綠用交響樂和搖滾樂交織的音符，在∞無限輪迴的舞台上，在圓形環繞的大螢幕裡，去表現他們心中音樂最美的那個樣子。沒有一個人可以看到全部，觀者只有自己全心全意的投入，才能看透這些華麗背景，無非是為了成就音樂本身，那種純然不需要解釋就已經被感動到淚流滿面的神奇力量。於是主唱青峰說：「終於有一次演唱會，我們不用去在乎那麼多其他表演的形式，我們只要在乎音樂應該做什麼事情，這對我們來說，是很純粹的一件事情。」「你們，跟我們一起拍了一部電影，這部電影，是音樂。這裡頭，所有的對白、劇情，只有音樂，我們只想用音樂、用作品說話。」
