Spiro have been together, their line-up completely unchanged, for over 20 years. That probably doesn't come as a surprise to those who've heard the four musicians in action: completely in tune with one another, there's no ornamentation to attract attention to one particular instrument. In fact, there's that feeling that each member of the band isn't just playing that instrument, they're playing the whole thing. This is what Spiro refer to as "the mesh", the locked-in ensemble sound that's a relentless, wonderfully overpowering assault on the eardrums.
