Born in '62 with older brothers who were in to Led Zep, Hendrix, Jethro Tull Moody Blues, Pink Floyd & Yes, still listening to them now.
In my 6th form days discovered Rush & Blue Oyster Cult , saw them both in '81 and probably say Rush are my all time greats.
Also picked up some 'newer' stuff via my youngest - now in his late 20's. Obvioulsy I initially indoctrinated him with my choices, but he's now passing a lot on to me, we typically would be going to 10-20 gigs a year.
Most of my go to list would be groups we seen live and mainly guitar based Rock bands / artists of various types inlcluding;
Fatherson
Biffy Clyro
Mogwai
Jimmy Eat World
Bob Mould
Coheed & Cambria
Billy Talent
Death Cab for Cutie
Placebo
Foo Fighters
ZZ Top
QOTSA
Devin Townsend
Alter Bridge & associated spin offs Myles Kennedy & Tremonti solo work
From holidays in France and some French TV shows got into Louis Bertignac - almost unknown in the UK, and recently got into couple of French prog Rock bands Klone & Gojira
But also got a bunch of people like Chris Wood, Martin Simpson, Andy McKee, John Gomm, Nik Kershaw (his post fame years stuff is quite different), Justin Currie who are still guitar based but probably more folky / acoustic edged.
Horrifying thing is realising that a lot of my 'new' young bands are now made up of 40+ year olds who have been around for 20 years or more.
