More Oar: A Tribute to the Skip Spence Album is a 1999 tribute album completed shortly before and released shortly after the death of Moby Grape founding member Skip Spence. The album contains cover versions by various artists of Spence's music from his Oar album, released in 1969, presented in the same order as on the original album. The album also contains a hidden bonus track of Spence's last known recording, "Land of the Sun", which was originally commissioned for the X-Files soundtrack, Songs in the Key of X, but not used.

Alexander "Skip" Spence was a Canadian-born American singer-songwriter and musician. He was co-founder of Moby Grape, and played guitar with them until 1969. In the same year, he released his only solo album, Oar, and then largely withdrew from the music industry. He had started his career as a guitarist in an early line-up of Quicksilver Messenger Service, and was the drummer on Jefferson Airplane's debut album, Jefferson Airplane Takes Off. He has been described on the AllMusic website as "one of psychedelia's brightest lights"; however, his career was plagued by drug addiction coupled with mental health problems, and he has been described by a biographer as a man who "neither died young nor had a chance to find his way out."
