The soulful sounds of "Liquid Jazz" will help raise funds Saturday evening for a Calvert County organization that provides medical care to uninsured patients.

The program, from 4:30 to 9 p.m. at the Show Place Arena in Upper Marlboro, will include jazz performances, wine tasting and a silent auction.

The evening's entertainment features the Gretchen Ritchie Jazz Cabaret, the Minor Thoughts Quartet and Roger Cador, the master of ceremonies. Ritchie, who has been playing in the D.C. area for the past 17 years, has recorded two CDs -- "Close Your Eyes," released in 2001, and "It Could Happen to You," released this year.

Tickets to the festival, hosted by Calvert Healthcare Solutions, are $65 and may be purchased through Ticketmaster at 202-397-7328 or www.ticketmaster.com or at the arena.

A class on the basics of wine tasting will be offered at 3:30 p.m. Saturday and is included in the ticket price. For more information, call 410-535-5595.

"A wonderful array of fine wines will be available for sampling during the event," Raymon Noble, a doctor and founder of Calvert Healthcare Solutions, said in a statement announcing the festival.

Items in the silent auction will include a two-night stay at a three-bedroom waterfront condo in Solomons, a Wurlitzer organ, a two-night stay at any Wyndham hotel, an Algonquin canoe and a trip to Hawaii.

Calvert Healthcare Solutions is a nonprofit organization that helps uninsured working adults in Calvert County with limited financial resources obtain primary medical care. The organization is a consortium of doctors who have volunteered their services to more than 750 adult residents since its inception in October 2002.

Money raised during "Liquid Jazz" will be used to pay for prescription drugs.
