Nostalgia reigns at Lake Tahoe, the scenic and romantic destination resort spot on the California-Nevada border. Sometimes the entertainment here can be more about great memories and less an ethereal thrill of witnessing something superb, unique and contemporary. There was the fat Elvis in 1976 and a raspy Bob Dylan in 2009. However, Peter Gabriel and Sting performed together in Stateline on Friday night in a show that left an everlasting impression on all 7,000 who attended. It was a thrill.
