Peter Hammill seems to be slipping gracefully into semi-retirement. Although there is apparently a new solo album on the way, when the most recent Van der Graaf Generator album, Do Not Disturb, came out last year, there was talk of it possibly being their last album. What’s more, Hammill’s formerly prodigious concert schedule is certainly less full than it used to be. It’s been five long years since I last saw him play a solo concert, which (happily for me) was at my favourite venue in the world, Porgy & Bess in Vienna. So it was a no-brainer to make the trip over to London for this mind-blowing three-night residency at what must surely be the smallest venue he’s played in Europe for years.
