In the difficult position of having to top "Saturday Night Fever", the Gibb brothers surpassed themselves and created their biggest hit studio album of their careers, including three more #1 hits, making six #1 hit songs in a row! "Tragedy", "Too Much Heaven" and "Love You Inside Out" were all top hit singles. "Spirits (Having Flown)" was a large hit single overseas. All songs are Barry dominated vocals and he is at his falsetto best. However, "Stop (Think Again)" is a tad long and a little bit tedious, but the following tracks go right back to their upbeat best! Succeeding in avoiding any dance songs (disco), the Bee Gees out-do themselves. These songs are truly funky "R & B" numbers, a solid match for any rythym and blues band. "Until", the closing solo track may not be equal to their earlier hit "Words", but Barry's voice accompanied by the electronic harpsichord makes for a delicious ending.
