[1][2] He fronted a handful of hard rock bands before joining them[citation needed] and currently has his own solo project, Hasse Fröberg & Musical Companion.

Foxtrot Records released their CD with the title Volume 3 in October 1994 on which Hasse did most of the writing and sang lead.

Hasse is also involved as lead singer and composer in Barrelhouse, a group that follows the hard road of the Zeppelin tradition.

"[citation needed] In October 2008, with The Flower Kings taking a break, Hasse decided it was time to form a new band.

The key to that I believe, is to find enthusiastic musicians who love to play my music and are willing to rehearse and to create a unit that really works well together."
