In the beginning
Back in 2007
Man knew about a rock 'n' roll show...
But Markus Grosskopf had something new:
He said:

"Let there be sound", and there was sound
"Let there be light", and there was light
"Let there be drums", and there was drums
"Let there be no guitar", and there was no guitar

"Let there be 4 basses" and there were 4 basses.
"Let there be Bassinvaders"

Markus Grosskopf (Helloween) invited some singing bass players such as Schmier (Destruction), Peavy Wagner (Rage) and Tom Angelripper (Sodom), to start his project: "Let's make a record without any guitars". In most metal bands the vocalists or the guitar players are the most famous. Why not put the bass players in the spotlight? Of course there are some bands where the bass player is the most famous, think of Lemmy, Steve Harris and of course Cliff Burton (R.I.P.). 

To complete his project he invited some other metal-friends, of course you can't do without drums, vocals and more.... bass players (hellbassbeaters). Billy Sheenan, Rudy Sarzo, Lee Rocker (StrayCats), Marco Mendoza, DD Verni, Wyzard, Dirk Schlächter, Joey Vera, Stig Pedersen, Nibbs, Tobias Exxel, Jens Becker, Dennis Ward, Peter Baltes and Michael Müller are also playing some bass parts (look up yourself in which band(s) they play). Guest drummers André Hilgers and Stefan Arnold together with the singers Apollo Papathanasio and the front man of the legendary Danish rock band D.A.D Jesper Binzer complete the pack. 

Enough heavyweights to make this a good album, but is it worth listening without the guitars? In heavy songs such as "Godless Gods, "Razorblade Romance" and "Dead From the Eyes Down" I don't really miss them. The Motörhead/Entombed kinds of songs are dark and heavy enough to do without. In songs as "Boiling Blood", "We Live" and "Far too Late", which are more in the style of Helloween and Rage, I do miss the guitars; the songs are a little bit empty without. The heavy songs often have grunts and raw vocals, the other melodic songs have clean vocals and sometimes are varying (clean/grunts). The track "The Asshole Song" gives me a Motörhead meets Black Sabbath feeling. The European bonus-track "To Hell and Back" is more pure Rock' n Roll and less metal, but very catching.

Summary: In every song there are nice bass-solos and licks. Every song is a decent written song and not just a view basses with drums and vocals. If you are a bass player, you must hear this record, even if it is just one time. I think this is going to be a unique collector’s item for everyone, who loves bass. A nice initiative and cool project, but as it is said in the dictionary, a project has to be temporary.
