More bands should do live albums. Boston-based Ethiopian groove orchestra Debo Band are as good a candidate as any. If their expansive new four-song ep Flamingoh (Pink Bird Dawn), recorded live on the band’s 2010 East African tour and available for five bucks at their bandcamp site, is any indication, their upcoming full-length concert cd will be unbelievable. Although they frequently indulge in the tricky polyrhythms in most Ethiopian dance music, this one grooves along to a pretty much straight-up 4/4. If these songs don’t make you move, you need to be defibrillated.

It’s amazing how interesting Debo Band can make a one-chord jam sound. Through all the catchy hooks, the hypnotic vamps, the funky grooves and sizzling horn motifs, there’s one chord change on the album. It’s on one of the songs’ choruses – that’s it. For those who listen to music from India, for example, that’s to be expected, but for music as funky as this, it’s quite a change. That it’s barely noticeable says a lot about how much fun it is. The six-minute opening track works a swaying, insanely catchy minor-key funk vamp with wah guitar, tight horns and incisive staccato violin accents from Jonah Rapino: he jumps on the hook and takes a juicy funk solo over the steady pulse of PJ Goodwin’s bass and the slinky shuffle of Keith Waters’ drums. Danny Mekkonen’s tenor sax sneaks in almost imperceptibly, then out, then in again with the rest of the section in tow. It’s a monster track. When’s the last time you heard a juicy funk solo played by a violin? Ever? That they’d have one pretty much speaks for itself.

The second cut has frontman Bruck Tesfaye singing lyrics in Amharic, careening along with wah-wah on the violin and snarling, distorted upper-register guitar from Brendon Wood. When it reaches the point where the interlocking guitar, horn and violin themes all mingle, it’s psychedelic beyond belief. The tension between squawking tenor sax and wailing electric lead guitar as the intensity rises slowly toward the end is typical of how this band works a crowd of dancers. A fervent, impassioned guest vocalist lends her powerful alto voice to the third cut, a bouncy, hook-driven joint with playful tradeoffs between the horns and Stacey Cordeiro’s accordion as it opens, followed by a seemingly endless series of oldschool funk turnarounds and a big fluttering crescendo at the end. The last cut works down to a mysterious, slinky reggae groove punctuated by a low ominous pulse from Arik Grier’s sousaphone, down even lower to a spooky dub breakdown, and out with a bang. Debo Band make frequent stops in NYC: their show last month at Joe’s Pub was characteristically fun. Watch this space for upcoming dates.
