Call him the Gangster of Love. Call him Maurice. You can even call him the Midnight Toker or Space Cowboy. Everybody knows that Steve Miller speaks the pompatus of love. Given all that it’s no wonder that the last three years have been the most busy, productive years in the long, illustrious career of Miller, an artist at the peak of his powers. He’s produced two new albums (“Bingo,” and its successor, “Let Your Hair Down”), completed numerous collaborations with other music greats and launched this tour. One of rock music’s all-time greats, the Steve Miller Band has sold more than 30 million records over 40 years. His trademark blues-rock sound has made him one of the key artists on classic rock radio.
