『Summer 4 Rhythm』（サマー・フォー・リズム）は、に発売された角松敏生通算15作目のスタジオ・アルバム。

解説 
「デビューまもない80年代初頭（イメージ的には83年リリースのサード・アルバム『ON THE CITY SHORE』あたり）にもし、今のテクニックやボキャブラリーを持っていたらこんなアルバムを作っていただろう」というテーマに基づいて制作されたコンセプト・アルバム。

沼澤尚（ドラムス）、青木智仁（ベース）、浅野祥之（ギター）、小林信吾（キーボード）の4リズムを核として、80年代前半の角松作品に対して一般的に形容されていた「海・夏・空港モノ」をテーマにした楽曲を中心に、往年のAORサウンドのエッセンスを取り込んだ楽曲を収録。

「波をこえて〜Over the Wave〜」は杏里に楽曲提供した「Over the Wave〜波をこえて〜 featuring Toshiki Kadomatsu」のセルフカバー（『R134 OCEAN DeLIGHTS』収録）。

初回盤は小林克也のDJスペシャル・ディスク『SUMMER TIME ROMANCE II? 〜SUMMER NIGHT ROMANCE〜 DJ.Katsuya Kobayashi』が付いた2枚組。
