For too long, underground dance music has been relegated to tiny spots that are practically as under the radar as the beats themselves. But the crowds that come out to join the parties aren’t nearly as small as the spaces they pile into. So local DJs and promoters Soul Clap, Taste, and Maximal Productions joined forces to bring true house and techno performers to the masses through their Radioland events at the Estate (One Boylston Place, Boston, 617.351.7000). The latest installment includes an appearance by UK-based globe-trotting DJ duo Peace Division. Before the main event begins, Radio-land resident DJs Jay Prouty and Maximal Production’s Brent G will spin. Tickets are $15 in advance at www.theestateboston.com and $20 at the door; the 21-plus event runs from 10 p.m. to 2 a.m.
