Rampant antiphonal brass and percussion characterise Smalley's Pulses for 5x4 Players – a huge and gripping work which uses electronic treatment of sound to explore the spatial relationship between groups of performers.

'Pulses is still fresh and impressive 25 years on, its sound growing inexorably like cumulus clouds... The performers [on the NMC recording] do the piece full justice, prompting a query as to why it has not been played more often.'
The Wire (1994)
