Lake Champlain. The festival attracted 70,000 attendees, making it both Phish's biggest concert crowd to that point and the largest single concert by attendance in the United States in 1996. Phish recorded their sixth album Billy Breathes in the winter and spring of 1996, and the album was issued in October of that year. Alongside traditional rock-based crescendos, the album has more acoustic guitar than their previous records, and was regarded by the band and some fans as their crowning studio achievement. The album's first single, "Free", peaked at No. 24 on the Billboard Hot Modern Rock Tracks chart and No. 11 on the Mainstream Rock Tracks chart, and was their most successful song on both charts. By 1997, Phish's concert improvisational ventures were developing into a new funk-inspired long form jamming style. Vermont-based ice cream conglomerate Ben & Jerry's launched "Phish Food" that year. The band officially licensed their name for use with the product, the only time they have ever allowed a third-party company to do so, and were directly involved with the creation of the flavor. Proceeds from the flavor are donated to the band's non-profit charity The WaterWheel Foundation, which raises funds for the preservation of Vermont's Lake Champlain. On August 8, 1997, Phish webcast one of their concerts live over the internet for the first time. On August 16 and 17, 1997, Phish held their second festival, The Great Went, over two days at the Loring Air Force Base in Limestone, Maine, near the Canada–United States border. In October 1997, the band released their second live album Slip Stitch and Pass, which featured selections from their March 1997 concert at the Markthalle Hamburg in Hamburg, Germany. Following the Great Went, the band embarked on a fall tour that was dubbed by fans as the "Phish Destroys America" tour after a 1970s kung fu-inspired poster for the opening date in Las Vegas. The 21-date tour is considered one of the group's most popular and acclaimed tours, and several concerts were later officially released on live album sets such as Live Phish Volume 11 in 2002. Phish ended 1997 as one of the ten highest grossing concert acts in the United States that year. In April 1998, the band embarked on the Island Tour - a four night tour with two shows at the Nassau Coliseum in Uniondale, New York on Long Island and another two at
