The clue is in the title, as the alternating rhythm sequence of clave, or key as its translated from the Spanish, is ever-present in this new project from Ireland’s Latin rhythm supremo. It’s a return to an idiom he loves, from his various salsa outfits and Latin jazz orchestras, and the emphasis here is on the latter, with a seven-man combo of Niall O’Brian (violin), Peter Dobai (sax), Barry McBrien (trombone). Leopoldo Osio (piano), Andrew Csibi,(bass) and Ed McGinn (congas/bata). Guilfoyle leads from the kit towards a fluid, jazz embrace of music from the Latin canon of artists like Oscar Hernandez.
