Take a million-dollar inventory of LPs, CDs and DVDs, arrange them on several 80-foot-long tables and place them into a 10,000 square foot room for three days.

This is the recipe for Capital Public Radio's (CPR) annual Used Record and CD Sale.

It will commence on Friday night with a "Preview Party" from 6 - 9 p.m. For a $20 cover charge, people can get a jump start on the musical feast while enjoying live music, food and wine.

On Saturday and Sunday from 10 a.m. - 5 p.m., the public can dig in for free and search through the leftovers. It all takes place in suite 172 of the "Howe 'bout Arden" shopping center at 2100 Arden Way.

All-in-all there will be approximately 45,000 vinyl records, 12,000 CDs, movies, cassettes, and "everything else," said event organizer Dennis Newhall, a DJ for KXJZ, 90.9 FM. "Everything else" includes old formats like laser discs, reel to reel, 8 tracks, and even beta.

About 40 percent of the vinyl is classical music, much of which is released only on vinyl, said Newhall. The other 60 percent is pop, rock, blues, jazz and other genres.

The CDs and cassettes include all these types of albums plus newer music like punk and hip-hop.

"The prices are great," Newhall said. They include $4 CDs and DVDs, $2 VHS tapes, and $1 LPs. As the stock dwindles, these prices will also decrease.

"I'm surprised at how many new CDs and DVDs there are," added Newhall, who planned the logistics of the sale.

Though a marketing team of four people is assisting him, the rest of the event is run by volunteers. People can still volunteer by signing up at capradio.org.

All the items were donated by CPR supporters in the last three weeks. They had been collected in bins at local Borders and AT&T stores.

For the last 15 years, people have been lining up at the doors before the sale. Thousands are expected this year.

"You snooze you lose," said Newhall of the sale. "It's just this weekend."

There will also be boxes of free items. These include CDs, cassettes and videos that are homemade or are missing packaging.

All proceeds go to CPR. CPR members will receive 50 percent off entrance to the Preview Party on Friday and 20 percent off all merchandise on Saturday and Sunday.
