It depends on the chronology. If the "ex or current members..." were touring when the Wild Zeros were formed (as in, the members met while they were on tour with their former groups and came together to form a new group, the Wild Zeros), then I'd use past perfect continuous. And I'd perhaps augment it with a phrase to make the series of events more clear.
The members had been touring all over France with their original groups [...]. This is when they came together to form the Wild Zeros.
But, it sounds like you are recounting the history of the group. If this is the case, then paste tense is fine:
The Wild Zeros were formed in Bordeaux in late 2007. They toured all over France, playing with bands such as The Zeros, Sonic Chicken 4, and Jerry Spider Gang and released a 7" and a 10" with Frantic City Records.
You also have a lot of sentence fragments and run-ons. Here are some things I would tweak:
The Wild Zeros started in Bordeaux in late 2007. Their first gig was in December of that year.
The second part was a sentence fragment. Add a verb to make it a sentence. You also may want to use "formed" instead of "started." The former has more of a connotation with bands.
Just a bunch of friends (ex or current members of Magnetix, Pneumonias, Mean Things, Skeptics, Wylde Tryfles…) who wanted to play Garage Punk music together and pay a tribute to their long time favourites such as The Troggs, DMZ, Penetrators and way more.
This is a pretty long sentence. I'd break it up:
They were just a bunch of friends who wanted to play garage punk music together and pay
a tribute to their long-time favorites such as The Troggs, DMZ, the Penetrators, and many more. They were former or current members of other groups such as Magnetix, Pneumonias, Mean Things, Skeptics, and Wylde Tryfles.
I wouldn't capitalize genres in sentence context. You "pay tribute" not "pay a tribute."
The next sentence is also rather long. I'd break it up:
As a group, they toured all over France, playing wit bands such as The Zeros, Sonic Chicken 4, and the Jerry Spider Gang. They also produced a 7" and 10" for Frantic City Records as well as a split 7" with The Baxx Sisi's for the Brooklyn-based Chickpea Records before taking a long break.
