Reviving the practice of using elements of popular music in classical composition, an approach that had been in hibernation in the United States during the 1960s, composer Philip Glass (born 1937) embraced the ethos of popular music without imitating it. Glass based two symphonies on music by rock musicians David Bowie and Brian Eno, but the symphonies' sound is distinctively his. Popular elements do not appear out of place in Glass's classical music, which from its early days has shared certain harmonies and rhythms with rock music.Yet this use of popular elements has not made Glass a composer of popular music. His music is not a version of popular music packaged to attract classical listeners; it is high art for listeners steeped in rock rather than the classics.
2.The passage suggests that Glass's work displays which of the following qualities?
A.A return to the use of popular music in classical compositions
B.An attempt to elevate rock music to an artistic status more closely approximating that of classical music
C.A long-standing tendency to incorporate elements from two apparently disparate musical styles

OG上给出的解释是“since G's style has always mixes elements of rock with classical elements",我觉得long-standing应该是和这个always的意思是一样的。可文中指提到了他在两部作品融入了摇滚元素,没体现出他经常这样做哎。或者是我的思路哪里有问题?
