His witty song cycle Craigslistieder (2006) was the catalyst for his growing success as a composer. His most recent project is the new musical February House, for which he wrote the music and lyrics, which had an extended run in New York City at The Public Theater in May/June 2012, and went on to record a Cast Recording. Entertainment Weekly reviewed February House saying that it was Kahane's "music and exceptional lyrics that carry the production into the sublime." In 2011, he released his second album, Where are the Arms. When Gabriel performs in a concert or cabaret setting, he “brings to mind Sinatra in his wee-small-hours mood,” according to The New Yorker, and his concert with the Los Angeles Philharmonic was deemed “an all around dazzling performance” by the Los Angeles Times.
