Erica Lindsay's tenor sax was first heard on the New York scene a decade ago, but she never recorded an album until now. She manages to compel interest without a huge sound or virtuoso dazzle. Her style is pensive, even dark, and she can sketch evocative melodies with a handful of notes. She's also an effective bandleader, working within an ensemble style that has its origin in '50s hard bop. All the selections on Dreamer except ''Day Dream,'' written by Billy Strayhorn, Duke Ellington, and J.J. LaTouche are originals. The versatile Howard Johnson provides winning support, especially with his tuba playing on ''First Movement.''
