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 by Pat Metheny , Michael Brecker , Avishai Cohen and Miguel Zenón . He leads a core quartet including bassist Scott Colley plus saxophonists Chris Potter and David Sanchez , with Metheny and Chick Corea as 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 of Joe Henderson 's "Inner Urge," playing freely against the twin tenor saxes, while Miles Davis ' "Solar" is an unusual guitar/drum duet with Metheny . Corea contributed the infectious Latin-flavored opener "One for Antonio," a trio number with Colley that showcases each of the musicians. The quartet is joined by Metheny for the guitarist's hypnotic Latin ballad "Arena (Sand)."
