Torbjørn Endrerud runs an art studio under the name tendart in Oslo, where he creates artwork inspired by music and lifestyle from the 1960s and 1970s. His style is characterized by the use of straight lines and strong colours, which gives the works a distinctive character. Endrerud offers both commissioned works and framing of art, which gives customers the opportunity to adapt the works of art to their own needs.
In addition to selling his own works through an online store, he actively participates in exhibitions at galleries around Norway. Endrerud specializes in lifestyle pictures suitable for cabins, and he also offers print services for other artists. Among his thematic collections is "The Beatles Collection", which highlights his ability to combine music history with visual art.
