Drummer Antonio Sanchéz's debut recording as a leader is an impressive outing. An alum of both Berklee and the New England Conservatory of Music jazz studies programs, the percussionist has appeared on CDs byPat Metheny,Michael Brecker,Avishai CohenandMiguel Zenón. He leads a core quartet including bassistScott Colleyplus saxophonistsChris PotterandDavid Sanchez, withMethenyandChick Coreaas special guests on selected tracks. The leader's four originals hold one's interest, especially his percolating"Challenge Within" and the alternately tense and freewheeling"Greedy Silence." Sanchéz dominates the delightful off-kilter arrangement ofJoe Henderson's"Inner Urge," playing freely against the twin tenor saxes, whileMiles Davis'"Solar" is an unusual guitar/drum duet withMetheny.Coreacontributed the infectious Latin-flavored opener"One for Antonio," a trio number withColleythat showcases each of the musicians. The quartet is joined byMethenyfor the guitarist's hypnotic Latin ballad"Arena (Sand)."
