There are at least three artists whose tracks lead to this profile:

1) Mighty Heavy rock, with Bluesy "Stoner" influences.

The Quill was formed in the early -90s in Sweden.

The original Lineup was formed by singer Magnus Ekwall, guitarist Christian Carlsson, drummer George Atlagic, Anders Haglund on Keyboard/Hammond and original bassist Peter Holm.
The lineup has changed a few times over the years with new bassplayers, and since 1997 Anders decided to leave. From that point the band have been a foursome and the current bassplayer is Robert Triches.

In their sound, which could be described as a modern 70's, one can find influences of bands like Black Sabbath and Led Zeppelin

They have also toured Europe as opening act to Monster Magnet and Glucifer.
