 Jarre 's follow @-@ up album , Équinoxe , was released in 1978 . It was composed with sequencers , particularly on the bass , and features a more baroque and classical style than Oxygène , with more emphasis on melodic development . Though its sales were still very healthy , it had less of an impact than Oxygène , but the following year Jarre held a large open @-@ air concert on Bastille Day , at the Place de la Concorde . The free outdoor event set a new world record for the largest number of spectators ever at an open @-@ air concert , drawing more than 1 million spectators . The crowds were so large that Jarre 's wife , Charlotte Rampling , found it difficult to access the venue . Although it was not the first time he had performed in concert ( Jarre had already played at the Paris Opera Ballet ) , the 40 minute @-@ long event , which used projections of light , images and fireworks , served as a blueprint for Jarre 's future concerts . Its popularity helped create a surge in sales — a further 800 @,@ 000 records were sold between 14 July and 31 August 1979 — and introduced the Frenchman to Francis Rimbert , who now works for Jarre on a full @-@ time basis .
