this album, recorded the same afternoon as three other records (relaxin',  workin', and steamin') with mr. davis's first stellar quintet (davis, john  coltrane, red garland, paul chambers, and philly joe jones), is a  masterpiece in every sense. mr. davis was in top form having now found his  own voice somewhere between dizzy gillespie's and clifford brown's  blistering bop trumpet and the west coast understatement of the horn.  "my funny valentine" could be played over and over again and  never stop revealing the nuances of the melody each soloist coaxes from the  tune as they improvise its theme. "airegin" lets us know mr.  davis could blaze right along with the best of them, but the closing ballad  "when lights are low," sets us free with another study for quiet  evenings and romantic fires. the quintet had jelled on this album and this  truly is a group piece. miles always gave his sidemen plenty of room to  stretch and even encouraged trios and duos to split off during the soloing  so each man could shine in their own way. a classic record.
