Strings have been very abused in pop music, usually doing little more than adding "sweetening." However, the strings are the most versatile section of the orchestra and are capable of a HUGE range of sounds and emotions. Too bad it's out of print, but an example of strings used to tremendous effect in an "orchestral pop" record is Les Baxter's "Caribbean Moonlight" album on Capitol. It's an album of latin-tinged standards arranged for percussion, winds, and strings (no brass), and the strings on this album are fantastic. With the right arranger/orchestrator, orchestral instruments and sections CAN be integrated into jazz setting, IMHO.
