In early 2002, Warner went on to expand his musical horizons when he joined the traditional Irish group, The McCabes. The McCabes breed of blistering Irish jibs and reels allowed Warner to experiment with new dimensions of sound and style, broadening his array of already accomplished and varied chops. The band performed on the popular Irish circuit of summer festivals, including a performance at Shea Stadium – the same stage of the Beatles record-breaking performance in 1965. Warner's performance with The McCabes was captured on their limited edition live release, The McCabes at Paddy Reilly's.
