Twin Sons of Different Mothers is a collaboration album by American singer-songwriter Dan Fogelberg and jazz flutist Tim Weisberg, released in 1978.

[3] The single "The Power of Gold" was added to the album at the last minute, due to the initial track they had planned on, had the piano out of tune with the orchestra, and it would have to be redone.

[3] Zollo goes on to say that Fogelberg figured "there was no sense in fighting it", so he then returned to the United States, and "went into the studio immediately to work on songs for his next album, Phoenix".

[4]Cash Box Magazine said the album "combines the talents of two performers in an experimental way" and "interestingly blends the folk-rock, guitar flavored elements of Fogelberg's music with Weisberg's more airy, free-spirited, flute laden sound".

[8] Author Dave DiMartino from Billboard Books, highlighted the "extraordinary version" of The Hollies "Tell Me to My Face", that "revealed an aspect of Fogelberg's rock roots that hasn't been on display since".

[11] American music critic Dave Marsh wrote in The Rolling Stone Record Guide that the album reminded him of "smooth post-rock cocktail-lounge Muzak".
