The Vintage Caravan formed in the municipality of Álftanes, Iceland in 2006, founded as teenagers by guitarist Óskar Logi Ágústsson and drummer Guðjón Reynisson, though the band did not function as a working unit until around 2009. Their sound synthesizes the psychedelic haze of Deep Purple with the crushing weight of stoner metal, delivered with a classic rock spontaneity. Six studio albums followed from their self-titled debut (2011) through Voyage (2014), Arrival (2015), Gateways (2018), Monuments (2021) — which reached number 21 on the German charts — and Portals (2025) on Napalm Records. Their longevity and consistency have made them one of the most productive acts in Icelandic rock.

Truckfighters formed in Örebro, Sweden in 2001 as a lean stoner rock outfit centered on the songwriting partnership of guitarist Niklas Källgren and bassist Oscar Boström. Their debut Gravity X (2005) on Fuzzorama Records established their fuzz-heavy, groove-driven approach, and follow-up Phi (2007) cemented their reputation in the European desert rock scene. The duo released five studio albums and returned after a decade-long hiatus with Masterflow.
