The new album from Portico Quartet, is another step forward. Producer Leckie has brought an extra clarity to their arrangements, while the musicians have made good use of the studio to sculpt and enhance their sound with loop pedals, real-time electronics and overdubs. Nevertheless, 70 per cent of the album was performed live at Abbey Road: this is a band who can deliver on the promise of their recordings in concert; and vice versa. Their collectively written compositions evoke a universe of musical possibilities and influences. 'Eventually, the sum of all our parts - and what we've been listening to - comes out,'</em> says Wyllie. Yet Portico Quartet sound like nobody else in jazz, World or contemporary music. Each of the nine tracks on Isla has a distinct mood and atmosphere, while remaining firmly within their soundworld. From the churning maelstrom of Clipper to the pounding pedal points of Dawn Patrol; from the fragile ostinatos of Line to the anthemic ensemble of the title track, Isla is an album whose contents reveal fresh nuances and facets on each listen.
