THE RENSSELAER SYMPHONY ORCHESTRA PLAYED “Beetho-ven’s 7th symphony,” “Overture Rienzi,” a medley of songs from The Gladiator, and other pieces, on Friday night in DCC 318. Their performance was attended by many, and the crowd seemed to have enjoyed the night’s musical entertainment. They are scheduled to play again this Sunday at Troy Savings Bank Music Hall at 2 pm with many other groups, a performance that is worth going to.
