Jussi Lehtisalo

Still the main project for Lehtisalo's musical endeavours, Circle have released 40 albums since 1994. Throughout the band's ever-shifting line-up, Lehtisalo has been the only constant presence, and de facto leader. The current core line-up of the band – Mika Rättö, Janne Westerlund, Tomi Leppänen and Lehtisalo – is the longest consistent incarnation of the group, and although their output has slowed down since the mid-2000s, Lehtisalo has shown no sign that he plans to wind the band up.

Jussi Lehtisalo (born 1973), is a Finnish bassist. In 1991 he founded Circle, a prolific band drawing influences from heavy metal and krautrock to develop a style of repetitive experimental rock. He also runs a record label, Ektro Records, releasing his own music alongside left field rock and metal releases by artists such as Faust and Acid Mothers Temple.

Lehtisalo is involved in a large number of projects outside of Circle, most notably Pharaoh Overlord, originally the trio of Leppänen, Westerlund and Lehtisalo indulging in a passion for stoner rock. He and Rättö have also released several albums as a duo (Rättö ja Lehtisalo) and one as a trio with Kauko Röyhkä. The improvisation-based Ektroverde uses various electronic instrument, jazz drumming, and 1970s-style progressive rock riffs. Other bands are Doktor Kettu, Steel Mammoth and Lehtisalofamily, which consists of Lehtisalo accompanied by his parents. Grumbling Fur, meanwhile, is a collaboration with Daniel O'Sullivan of Guapo and Alexander Tucker, amongst others. 2012 saw the debut release from Split Cranium, a collaboration with Aaron Turner of Isis.
