Christian McBride & Inside Straight, Kind of Brown (MackAvenue). The bassist sets aside his fascination with rock, hip-hop and electronica to cruise the mainstream. He uses only his acoustic bass. The music is latterday bebop, with a few modal tinges. Alto saxophonist Steve Wilson, always impressive, is at a peak here. His unison lines with young vibraphonist Warren Wolf are an attractive element. Eric Reed and Carl Allen are on piano and drums. After nine tracks of hard swinging, McBride picks up his bow to beautifully intone the melody of Jimmy McHugh’s “Where Are You?”
