Lora Logic (also spelt Laura Logic; born Susan Whitby c. 1960) is a Britishsaxophonist and singer. She was briefly a member of the bandX-Ray Spex, although she had been sacked from that group by the time they recorded their first album, which nevertheless used her (uncredited) saxophone arrangements. A year later she formed Essential Logic. This group recorded one self-titled EP, four singles and an album, Beat Rhythm News (Waddle Ya Play?). Logic was briefly also a member of Red Krayola, appearing on two singles and the album Kangaroo?. Her saxophone lent a unique quality to the bands she was in. She also played on recordings by The Raincoats, The Stranglers and Swell Maps and, later, Boy George. During the recording of the second Essential Logic album the group broke up, and she finished the recording as a solo Lora Logic album, Pedigree Charm.
