Machiavel is a Belgian band that started off late 70's and has 8 vinyls and about 15 CD-releases. Mostly the band brings some Symphonic rock orientated music that some of you maybe like (in the 80's they tended a bit more to AOR/poprock music), here's a 15 minute video from a concert they played in March;
