It's my least favourite of his solo albums (still great though) but PG1 must be one of the most eclectic records in my collection. From quirky prog (Moribund) to complex pop-rock (Solisbury) to barbershop quartet (Excuse Me) to an extraordinarily beautiful ballad (Humdrum) to soft jazz (Waiting for the Big One) to weird Wagnerian thundering brass sections married to an even weirder disco-rocker (Down the Dolce Vita) to an iconic hair-raising anthem (Here Comes the Flood). In its way it's every bit as off-the-wall as his previous one with Genesis, Lamb Lies Down on Broadway. I love its exuberance and sense of total artistic freedom, even if I don't exactly like all the songs.
PG2 I absolutely love though. Such a beautiful, intimate record. It's an album for this very season and I play it a lot during the dark winter months. It's mainly known for On The Air and DIY, but Mother of Violence, White Shadow, Flotsam and Jetsam, Indigo and the sublime Home Sweet Home would easily make my top 20 Gabriel tracks.
PG4 is his masterpiece and a top ten album of all time for me.
