The physically astounding and fluid dancers of the Alvin Ailey Dance Theater bring their breathtaking moves to Ruth Eckerd Hall tonight. The theme for tonight's show is an expanded take on a perennial favorite, Revelations. Considered a signature work, Revelations draws upon the late founder's "blood memories" of Texas, translated through the blues, spirituals, and gospel music. Ailey originally intended the dance to be the second part of a larger, evening-length survey of African-American music which he began with Blues Suite — and now the company is bringing his vision to fruition. Explore the gamut of grief and joy, celebrating the essence and cultural heritage of the African-American and a moving tribute to the late-great Ailey. Could there be a better way to celebrate Black History Month? 8 p.m. $37-$58. Ruth Eckerd Hall, 1111 McMullen-Booth Road, Clearwater. 727-791-7400. rutheckerdhall.com.
