These recordings were subsequently issued as the Preflyte album on Usher 's own Together Records imprint in July 1969 . Although the material on Preflyte was five years old at the time of its release , the album actually managed to outperform Dr. Byrds & Mr. Hyde in America , garnering moderately enthusiastic reviews and peaking at number 84 on the Billboard album chart .
