Thin Lips is a dialogue between music and poetry, a collaboration between the Israeli poet Karen Alkalay-Gut, and musicians Roy Yarkoni and Ishay Sommer.

Thin Lips began with its first album, released January 2004, and continues with developing performances at venues as varied as the Barby night club and Beit Levick, the home of the Israel Association of Yiddish Writers. Alkalay-Gut performs in English, Hebrew and Yiddish to the exciting and original music of Roy Yarkoni, Ishay Sommer, Yatziv Caspi, and Erez Kariel as well as a variety of guest artists and musicians.

Yarkoni and Sommer created music which combines a number of musical genres and styles, among them progressive rock, jazz and classical music, which in combination with the poet’s dramatic voice, "moves between lust and satisfaction, between hunger for knowledge and the wisdom of knowing," and asks only to "seize the current moment."
