The inaugural Famously Hot Music Festival is a three-day festival that is separated into three nights of genre-specific music: EDM Friday, rock Saturday and country Sunday.

The festival, which runs today through Sunday in Finlay Park, has only one stage, so organizers booked the festival to maximize audience draw. The reasoning is simple: If a music fan likes, say, rock, that fan is probably more likely to buy a ticket for a daily lineup featuring five rock bands instead of seeing one rock band play on a varied lineup. (Even if the rock bands are now known as nostalgic acts? That remains to be seen.)

A total of 15 performers will play on the Famously Hot Stage.

Friday (gates open at 2 p.m.)

EDM: A brief introduction for the uninitiated: EDM — an abbreviation for electronic dance music — is an amalgamation of various club music subgenres — jungle, house, trance, etc. — from the ’90s and ’00s.

The rave culture, once celebrated for and gravitated to because of its subversive intent and the illicit drug use, is no longer in opposition to pop culture. It’s now part of the fabric. The DJs, who use computers, turntables, mixing consoles and iPads, in the scene are global; they are rock starts. EDM even has its own Grammy category, as the genre’s synthesized foundation and robotic filtering of vocals has infiltrated pop music radio. Singers from Britney Spears to Katy Perry to Chris Brown have co-opted the EDM sound that originated in dance clubs. EDM has become big enough to sustain its own large, multiday festivals.

In the dance clubs, though, the sound is morphing at a rate much faster than pop music’s reproduction and refitting can keep up with. EDM subgenres (some with their own subgenres) such as break, dubstep and Hi-NRG continue to evolve on the dance floor. One thing remains paramount: the break, the space of air, sometimes filled by instruments, before the drums return with bombast. Therein lies EDM’s kinship with all rhythmic genres and, by extension, all music: where the drum beat hits is so important.

2:45-3:45 p.m., Minnesota: Post-industrial dance music. It’s a sci-fi fan’s fantastic nightmare, what the next reboot of “Total Recall” should sound like.

4:15-5:15 p.m., Archnemesis: The music endures a warping effect when manipulated by this sample-heavy duo. You’ll probably hear something you recognize.

5:45-6:45 p.m., Eliot Lipp: The producer makes music that doesn’t have to be demarcated as EDM, even though his music retains some of EDM’s vestiges like throbbing bass lines and truncated transitions. In other words, Lipp blends extremely well. Next weekend, he’s playing the Electric Zoo Festival headlined by the kings of EDM, Skrillex, David Guetta and Tiesto.

7:15-8:15 p.m. SAVOY: The respected trio of EDM producers embodies the hip quotient of the genre, which is why SAVOY is playing Jay-Z’s “Made in America” festival next month in Philadelphia. SAVOY’s music is laser sharp with an impressive melding of titanic breaks and swarming vocal production.

8:45-10 p.m. EOTO: Michael Travis and Jason Hann use various instruments, including keyboards, guitars and drums, computers and looping software to create a dynamic live set that essentially redefines what live electronic music is. EOTO formed as a side project to The String Cheese Incident, a popular jam band.

After party: The Famously Hot EDM Cool Down After Party will be held at Red Hot Tomatoes, 632 Harden St. More DJs, including some local, will perform. $10

Saturday (gates open at 2 p.m.)

ROCK

2:45-3:45 p.m., Eve 6: The alt-rock band had two big hits in “Here’s to the Night” and “Inside Out.” After disbanding, the trio has reunited to ride rock music’s nostalgic wave.

4:15-5:15 p.m., Seven Mary Three: In the mid-’90s, the band slid in between the grunge of Nirvana and Pearl Jam and the pop-rock of Hootie and The Blowfish. It must not have been a “Cumbersome” position, because that was the title of the band’s massive hit.

5:45-6:45 p.m., Filter: The band introduced themselves to radio with the industrial-rock of “Hey Man, Nice Shot” before getting into balladry with “Take a Picture.”

7:15-8:15 p.m., Buckcherry: Wrist-cuff alt-rock with a sex-and-drugs attitude. That doesn’t mean there isn’t a soft side or that the band can’t say “Sorry.”

8:45-10 p.m., Collective Soul: A benefactor of Hootie’s success, the Georgia rockers did what Hootie couldn’t: sustain chart-topping popularity. Collective Soul had a number of No. 1 rock hits, including the memorable “Shine,” “Heavy” and “The World I Know.”

Sunday (gates open at 1 p.m.)

COUNTRY

1:45-2:45 p.m., Julie Roberts: The South Carolina native’s song “Sweet Carolina” is being used to promote USC’s historic $1 billion campaign — Carolina’s Promise.

3:15-4:15 p.m., Josh Thompson: Thompson’s “Beer on the Table” is one of the best 9-to-5 songs since Dolly Parton’s “9 to 5.”

4:45-5:45 p.m., Pat Green: He plays Texas country music, which is to say he’s a long way from Nashville’s pop-country. Contemporary country just isn’t his style.

6:15-7:15 p.m., Corey Smith: Smith has put together a concoction of country, blues and rock to form a sound that has endeared him to a loyal following.

7:45-9 p.m., Lonestar: The harmony-laden Texas band is celebrating 20 years together.
