Basically after the commercial failure of Big Canoe Tim had no record company interest. Thankfully, at the same time, Crowded House was making it big in the US. Neil threw his weight around and convinced Capital Records that, if paired with producer Mitchell Froom, Tim could make a great record. So Neil single handedly resurrected Tim's solo career (not a bad return for Tim after inviting Neil to join the Enz).
Mitchell pulled together Peter Gabriel's support band to play the backing tracks and Tim Finn (1989) was born. Tim never toured to support the album stating that any sort of tour really needed a hit song to support it. He never got that hit so he just did some promotional gigs.
For the longest time I thought that this was the album after Tim broke up with actress Greta Scacchi, but it turns out that wasn't until July of 1990. So Before & After is actually the big post-breakup album.
