Famous quotes containing the words roll and/or angle:
“As I define it, rock & roll is dead. The attitude isn’t dead, but the music is no longer vital. It doesn’t have the same meaning. The attitude, though, is still very much alive—and it still informs other kinds of music.”
—David Byrne (b. 1952)
“Modesty is the only sure bait when you angle for praise.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
