||By 1969, black artists were following rock's lead and recording extended epics. At the forefront of such experimentation was big bad Isaac Hayes, coauthor of countless Stax classics and an artist in his own right. On this, his second album, Hayes takes two MOR-pop benchmarks, Burt Bacharach's "Walk On By" and Jimmy Webb's "By the Time I Get to Phoenix," and spins them out into slow-building sermons lasting 12 and 18.5 minutes apiece. Heavily romantic, they predate by two years Barry White's symphonic adventures in the same style, revolutionizing soul music in the process. Meanwhile, on the album's third epic, the 10-minute "Hyperbolicsyllabicsesquedalymistic," Hayes and his backing band the Bar-Kays wind up sounding, bizarrely, like a black Crazy Horse.
