Devil Side Festival Bands Announced; Are One Day Events the Way to Go?

A few hours ago I got a press release announcing the Devil Side Festival at Landschaftspark in Duisburg-Nord, Germany. The one-day festival is June 28 and will feature these bands:

All Shall Perish
Anthrax
Bloodhound Gang
The Bones
The Carburetors
CRO-MAGS
Discipline
Disco Ensemble
Elvis Jackson
Five Finger Death Punch
Hammerhead
Millencolin
Misfits
Motorhead (headliner)
Peter Pan Speedrock
Soulfly

Personally, I think this is a great one day Metal lineup. The more I think about it - perhaps one day fests are the way to go. On the Glammer side of things, both the M3 Fest (Baltimore, Maryland) and the Desert Invasion (Phoenix, Arizona) have great lineups. M3 features:

Twisted Sister
Ratt
Extreme
Kix
Slaughter
Dokken
Y&T
Gilby Clarke
Jani Lane
Keel
Jetboy
L.A. Guns
XYZ
SLAMM

The Desert Invasion features:

Dee Snider (host)Night RangerSkid RowL.A. GunsTrixterKixBulletboysFirehouseBang Tango

The way the economy and tour routings are going this year, it seems that more and more promoters are cashing in on one and two day events that give fans the festival experience without the expense of a week-long vacation.

At any rate, I won't be at any of these three events because I went ahead and signed up for more traditional, multi-day fests. Still, if I had an infinite amount of cash, you'd better believe I'd be at M3 - no question.
