The Doobie Brothers -- one of the iconic rock bands of the 1970s and early '80s -- will appear at the Levitt Pavilion Thursday in a concert that benefits the outdoor venue's free programming. With hits such as Black Water, Listen to the Music and Jesus is Just Alright, the band in its heyday won three Grammy Awards. The $95 seats are in a preferred section while the $250 tickets include premium seating, a pre-concert reception with open bar and hors d'oeuvres and an after-party with dessert.
