Great topic!
Here's my personal Purple Tree:
Oct. 27th 1993: Deep Purple MKII (reformed) @
Stadthalle, Vienna
I still have the ticket, the Tour Programme, and I bought a Machine Head T-Shirt that night!
The gig was just awful. I remember waiting for an eternity after the support act (Austria's Alkbottle) because there was trouble with the Laser Show.
And Gillan punched some idiot in the first row who wanted to take the stage with the mic stand in the face.
Paice had sort of a night off (the drum solo was specially uninspired) Blackmore and Lord had stone-cold faces throughout, and Glover tried to hold the whole thing together...
May 16th 1995 The British R'n'B Show @ Rockhaus, Vienna
feat. Purple/Whitesnake alumni Tony Ashton, Colin Hodgkinson & Pete York, amongst others.
There was some football game on the telly the same night so the venue was half empty.
I remember this being one of the best concerts I've ever been to.
Tony Ashton stole the show when he walked on stage with a bottle of beer in his hand and a cigarette in his nose!

He then put the cig into the (well documented) wide gap between his two upper front teeth!
I also went backstage after the gig and got various items signed by messrs Ashton, York, Spencer Davis, Miller Anderson & co. and remember vividly chatting with Colin Hodgkinson about (you guessed it) bass playing...
I saw the Spencer Davis group (again with Hodgkinson but sans the other guests) on April 27th 1997.
July 5th 1997 Deep Purple with Steve Morse @ Sommerarena, Vienna (Openair)
Unfortunately I had missed both the Satriani line-up and the
Purpendicular show, but I went to see the band on their
Abandoned Tour here in Vienna.
The show was still excellent, but probably not as good as the reviews from the
Purpendicular Tour had been.
I still have the ticket and the Tour Programme.
Sept. 17th 2002 Hughes-Turner Project @ Planet Music, Vienna
My first Glenn show!
Glenn had a little accident just before the show when he mistook a bottle of vinegar for water. He was very uncomfortable for about half an hour. But when they got to
Seventh Star he suddenly seemed to feel better, let out one of his trademark screams during the keyboard intro, and I had tears in my eyes..
I still have the ticket - and a recording of the show on CD-R, thanks to an unnamed forum member from up north.
June 2nd 2003 Whitesnake @ Kurhalle Oberlaa, Vienna
Bonfire were supporting, but I missed them due to endless lines at the bar. What I heard from the outside I didn't miss anything though.
I had a very good view, spot on Marco Mendoza and Reb Beach and caught one of Reb's picks after the first song, which I gave to my friend Robert.
Coverdale was in good form for about one third of the set, but still had a lot of fun chatting with the audience in the second half. E.G.:
Hey, is this your girlfriend? - you two should be doing something else right now...
I still have the ticket.
March 3rd 2003 Hughes-Turner Project @ Planet Music, Vienna
The second HTP show in Vienna, low attendance, unfortunately, about 300 people. I remember this being very very loud and not as good as the first one (but still great!) with JJ in exceptional form! People were waiting in front of the backstage door for autographs after the show, but I spotted Glenn & Co sneek out through the stage exit. I managed to say hello to Glenn & JJ in front of the venue, and Glenn said "Hi guys!" and disappared in the bus. Security was strict and tight that night...
I took some pics, still have the ticket and the Tour Flyer.
March 22nd 2005 Glenn Hughes @ Komma, Wörgl (Tyrol)
The show was cancelled an hour before it was on due to food poisoning. I only realized it at the door, after an 4 hour drive all through Austria.
Still disappointed because FFF was on sale that night, and I didn't get a copy because all the merch was already stowed away in the bus...
June 26th 2006 Billy Joel @ Stadthalle, Vienna
Billy Joel, WTF, you're probably thinking!?
Chuck Burgi on drums and Dave Rosenthal on keys!

I still have the ticket and the Tour Programme.
July 7th 2006 Keith Emerson Band @ Legends Of Rock, Wiesen
Marc Bonilla played guitar in Emerson's band! Loved every second of the show, though it would have been more fun, hadn't I poisoned myself from either the food or one of the drinks (beer in cups - a don't for me ever since!)...
Still have the ticket and a couple of pics.
November 19th 2006 Glenn Hughes @ Divadlo Arena, Bratislava
The security guy at the door asked me (in his best English) if I carried a gun!? The support act played film music as a power trio, which was fun.
Glenn's performance was memorable, and I had tears in my eyes during Mistreated.
More thoughts on the show in the thread from back then somewhere here on the forum.
I missed Glenn again after the show, because we had a rather long walk to the car and decided to leave only minutes before Glenn & co. met the fans in the foyer...
That's it for now.
Hope I didn't miss anything!?
Cheers,
Christian
