Twelve-inch records are spread across the carpet in the small bedroom where five young men joke, create music and listen to it.
Corners of thin cardboard holders stick out of plastic crates on the sand-colored floor. Next to the crates is a clear toy box with two giant stuffed Powerpuff Girls dolls. Their paper-plate eyes gaze intently.
Hundreds of records are categorized neatly on three levels of a 6-foot tall shelf. On the wall is a Bear Creek High School diploma.
Black vinyl discs -- recordings by Alicia Keyes, Earth, Wind and Fire and Del the Funky Homosapien -- are strewn on a twin-sized bed next to two old-school Technics turntables.
Alvin Peebles, a beefy 22-year-old in a faded gray
T-shirt, olive cargo shorts and matching green hat, moves the fingers of his right hand with precision while spinning records.
With his left hand, Peebles pinches the silver knob on the scratching mixer, moving it back and forth. Pieces of voices and bits of music permeate the room.
Meanwhile, Darrell Pierce, 22, a friend of Peebles, is toying with a desktop computer -- thumping out a high-tech bass line.
The huge black leather chair he's slouching in makes Pierce's skinny frame look even smaller as he adjusts the knobs and switches on the screen.
The evolution of scratching, a basic element of hip-hop, is starkly revealed in the rear room of this single-story, tan stucco house in north Stockton.
Stockton beat junkies such as Peebles, with his '70s-style turntables, and Pierce, with his post-millennial computer, are carrying on the tradition established 30 years ago by young trailblazers in the South Bronx and other New York City neighborhoods.
"Aw yeah," grunts Pierce to the screen. "We're taking it to that other level."
They illustrate the ongoing evolution of hip-hop DJs from rudimentary record scratching to technically proficient production skills.
Advancements in technology -- and the increased mixing of R&B, rock and jazz by hip-hop DJs -- have made scratching more accessible, helping it flourish in the mainstream while influencing other musical genres.
"A big reason is more people can afford to have home studios," said Jason Leal, 22, a Stockton producer and MC who creates synthesized, less bass-heavy tracks. "Back in the day, a lot of people couldn't afford to go to a big studio. Now, everybody has them (at home)."
It's an underground movement that is flourishing.
"We don't have the support, but that's not going to stop us," he said. "This is creative freedom."
Although its roots are in New York City, the Bay Area influence is evident in Stockton, say local DJs and producers.
They've moved beyond simple baby scratches -- where the DJ moves a vinyl record back and forth under the needle -- to more intricate and rhythmic movements with their fingers and wrists.
There are also different types of DJs. Party DJs spin popular records while battle DJs, known as turntablists, display their skills at competitions.
There's no limit to where scratching can go, said DJ Qbert, a well-known San Francisco performer whose real name is Richard Quitevis.
"You can do whatever you want," said Quitevis, 32. "You can mix punk, rock, jazz into hip-hop. So it keeps growing."
Leal, a soft-spoken former graffiti artist known as Damage, isn't waiting. In fact, he taps his computer keyboard to create scratching sounds and full-length albums.
On one side of his narrow, second-story studio in west central Stockton, Leal has his recording equipment wired to a desktop computer.
With the appropriate software, the entire system, which cost between $3,000 and $4,000, allows Leal to record, program, master and mix music.
It also enables him to scan images and design album covers and posters.
His apartment is so cramped, his recording studio is crammed into the kitchen. He can open his refrigerator without leaving his chair.
He saves money by recording his own rhythm tracks. They'd cost between $100 and $500 if he had to buy them from other producers in Stockton.
Though he relies upon cutting-edge computer technology, the tracks don't have to be clean.
"It doesn't matter if it sounds a little dirty or gritty," Leal said. "That's how it always sounded."
Mike Lawson can relate to that.
Some closets are bigger than The Shack, Lawson's south Stockton studio. He converted a storage shed in the back of his duplex in Conway Homes.
Behind a maroon curtain, the 34-year-old Lawson's bulky frame sits next to a dusty, dated four-track mixer and recorder, drum machine, amplifier, speakers and CD burner. The basics, he calls it.
Known as "Mike D.," Lawson was a DJ in the 1980s before rhyming and producing tracks with C.O.P.S. (Criminals Over-Powering Society), a local rap group. The 1987 graduate of Edison High School also created beats for local rappers and crews such as Trellmixx, H.C.U. and Killa Tribe.
He's recorded in 32-track studios with more than $1 million in equipment, but it didn't help him get "that sound."
"A lot of people got (a lot of expensive) equipment and still can't get that sound," Lawson said. "If you ain't no good at working on a computer, it's not going to work."
Anthony Payne, a Stockton resident who calls himself DJ Smash, moved from collecting funk records, rocking house parties and battling other turntablists to producing tracks for E-40 and Too $hort.
Payne, 33, paid attention to East Coast hip-hop pioneers such as Grandmaster Flash, Kurtis Blow, Marly Marl and Los Angeles-based Dr. Dre as they evolved from DJs to producers.
"The transition is something that gets swept under the rug or paid little attention," Payne said. "The industry is producer-driven now."
Thanks to modern technology, recording tracks has become much easier. Instead of hauling around a drum machine, electronic keyboards and mixers, Payne works with touch-screen keyboards such as the Trinity Triton to build his tracks.
Now, all he needs after perfecting beats on computer software -- which duplicates the sound of professional studio equipment -- is a floppy disk.
Rob Principe, who runs the Scratch DJ Academy in New York City, said scratching is more popular than ever, but the skills still are hard to master.
"DJs are taking music and changing the composition and arrangement by adding scratches, cuts and breaks," said Principe, who started his Manhattan school in February with Run-DMC's Jam Master J and author Reg E. Gaines.
The 28-year-old provides his 1,400 students with equipment and instruction. They start by learning the basic parts of a turntable and simple scratches, while DJs such as Premier and Evil Dee offer guidance.
The academy's goal is to legitimize and validate scratching, which should be studied in universities like jazz, Principe said.
"Unless you know someone or are looking at someone spinning records, and digging into the crates, you won't learn about it," said Principe.
HOME STUDIO EXPLOSION: Jason Leal, 22, of Stockton, is one of a growing number of local producers who have invested in sound equipment to build a home studio. With the appropriate software, Leal's system, which cost between $3,000 and $4,000, allows him to record, program, master and mix music, as well as scan images and design album covers and promotional posters.
