Huw Warren, the Welsh pianist-composer, has key influences so wide-ranging it's impossible to box him in. Among others, his work has oscillated between the pastoral jazz quartet Perfect Houseplants, a long-time collaboration with the contemporary folk vocalist June Tabor currently in ECM trio Quercus with Iain Ballamy, through solo piano projects – the brilliant John Dowland tribute Infinite Riches in a Little Room on Babel in 2001 – favouring early-baroque music to Township and Brazilian jazz through to minimalism and avant-garde. It might be why Warren has been something of an unsung, yet idiosyncratic, figure in UK jazz since the 1990s. Joined here by his son Zoot Warren on drums and long-time bass partner Dudley Phillips, Everything In Between reignites Warren's love of Brazilian music and the maverick composer Hermeto Pascoal – he released a glowing tribute Hermeto + on the Basho label in 2009 – along with sumptuous interpretations of a pair of compositions by Chico Buarque and Egberto Gismonti. He brings a perfectly executed lilt to Hermeto's ballad ‘Mente Clara’ and Chico Buarque's ‘Choro Bandido’. These are the highpoints, but the other half of the compositions written by the bassist Phillips and Warren, maintain the upbeat mood, indebted to South African and Brazilian jazz, as well as a romantic pianistic lineage that joins Bach and Debussy to Bill Evans and Keith Jarrett. As is the case with much of Warren's work, this is airily graceful and unpretentious music.
