Some established artists moved towards music that was simpler and more commercially viable. Arena rock bands like Journey, Kansas, Styx, GTR, ELO and Foreigner either had begun as progressive rock bands or included members with strong ties to the genre. These groups retained some of the song complexity and orchestral-style arrangements, but they moved away from lyrical mysticism in favour of more conventional themes such as relationships. Genesis transformed into a successful pop act, and a re-formed Yes released the relatively mainstream "90125" (1983), which yielded their only US number-one single, "Owner of a Lonely Heart". These radio-friendly groups have been called "prog lite". One band who remained successful into the 1980s while maintaining a progressive approach was Pink Floyd, who released "The Wall" late in 1979. The album, which brought punk anger into progressive rock, was a huge success and was later filmed as "Pink Floyd – The Wall".
