Two styles of music relatively obscure in your average record store, but alive and kicking online, are the flourishing nu-jazz and broken beat genres. Nu-jazz encompasses pretty much anything in the “leftfield jazzy beats” realm–from downtempo acts like Mr. Scruff or Cinematic Orchestra to uptempo sounds from Jazzanova or Sleepwalker. Broken beat is a sound attributed to London-based artists like Bugz In The Attic and Mark de Clive-Lowe, but produced globally as well.

There’s no better place for the average music fan to get a dose of these musical flavors than on the plethora of international online radio broadcasts. Here’s our guide to a few of the best.

Since 2003, Philly’s Broke N’ Beat Radio has offered exclusive mixes from some of the world’s best nu-jazz purveyors. Patrick Forge, Rich Medina, and Domu (pictured) are among the many DJs whose sets are available in the site’s archives. Primarily run by DJ Argo, a recent show that featured tracks from Azymuth, Slope, Simbad, Lanu, and Inverse Cinematics. And if you missed a stream, you can always have it delivered to your iTunes folder as a podcast.

Simply put, Australia’s Straight Up features radio shows, interviews, live sets, and guest mixes from some of nu-jazz’s and downtempo’s best artists. A visit to the site recently revealed offerings such as an exclusive guest mix by the pieman and tea drinker from Manchester, Mr Scruff, a live set from Tru Thoughts artist Alice Russell, and interviews with 4hero. And did I mention the site’s 20-strong, multi-genre radio DJ line-up? Killer site, all-around.

Put me close to a computer, and before long I’ll probably be surfing over to Samurai.FM for whatever dope exclusive DJ mix it has in rotation. The other day John Tejada was live-cast from the Yellow club in Tokyo, followed by web-DJ sets from Amsterdam’s Aardvarck, Germany’s Luciano, and USA dub cats theAgriculture. Also, Samurai’s artist- and label-profile section has an “A-to-Z” of coolness, from Herbert’s Accidental Recordings to Brighton hip-hop label Zebra Traffic. Tune in.

You have selectors and you have selectors. Matthias Desch is a DJ’s DJ, knowing just how to program and select a swath of devastatingly dope tunes. His Munich, Germany-based Boogaloo Radio gets right down to business each week, with a compressed set of excellent new music. In between the exclusive tracks, you’ll hear lovely business from labels like Kindred Spirits and Sunshine Enterprises. Subscribe to the RSS-Feed.
