Just to add a note of disagreement on the one star review above. This was my first introduction to Gunn's poems, and I found them accomplished, elegant and deeply moving.
Gunn maintains the formal poetic structures of his english roots (he went to Cambridge during the 50s and was influenced by his english contemporaries) with delicate metres and rhyme schemes. But he enthuses these with the informalism of theme and idiom from his Californian and American neighbours and friends after moving to the states in the sixties - admiring the beats, and their lifestyle, but never letting his own structured verse collapse.
This collection reflects the strengths of both these approaches, and with laments and memorials to lost friends and lovers to HIV (and puzzlement at his own survival) it sounds immediately fresh, honest and also with depth and wonderful surprises unveiled by reading aloud (preferably in bed at night to those you love). If in doubt read 'To Isherwood Dying'.
