Southern California is the record pressing capital of America, which, in these heady days of the so-called vinyl revival (the format still only accounts for less than 1 percent of total music sales), means something. We've got Bill Smith Custom Records in El Segundo, Erika in Downey dishing out wax tracks for Southern Lord and Sublime Frequencies, and there is Rainbo in Canoga Park specializing in colored vinyl and picture discs. Each makes quality slabs that sound beefy on your hi-fi. But to get the records that, to our professional ears, have the most gravitas, travel up the 101 to Camarillo, where Record Technology, Inc. runs the vinyl press nonstop. Don't believe us? Ask Sub Pop, Matador, Tompkins Square, Rhino, Merge and a host of other top-tier vinyl-friendly labels, all of whom use RTI. On the day we visited last year, they were busy pressing up the already-classic Fleet Foxes debut, full-length. Too futuristic to worry about LPs, superstar DJ? RTI also makes the Serato brand coded vinyl, which, with the right software, connects MP3s with your Technics 1200s. 486 Dawson Drive, Camarillo. (805) 484-2747, recordtech.com.
