Best of Vegas is a 2011 live album by American singer Frank Sinatra that contains 17 live tracks from the 2006 box set, "Sinatra: Vegas". In the span of a few years, Las Vegas refueled Frank Sinatra's career and Sinatra in turn became the lead figure in the city's ascendance. It was a synergistic relationship that has since become legendary in the annals of 20th century entertainment.
