Gaia's
show at Irvine Contemporary just opened - and Gaia hit the streets to announce his arrival. There are more complicated pieces (including his 'Grandfather' and bird figures), but I find this piece,
'Cease' is really striking - particularly on a boarded-up church.
You can see more of his street work
here, and the show runs until July 24 -
details here.
