There is more than one artist named Quicksand:

1) Quicksand was one of the most influential New York post-hardcore bands of the early to mid-90's, led by Gorilla Biscuits mastermind/guitarist Walter Schreifels. Quicksand provided the blueprint for many bands to follow in their footsteps. British bands such as Hundred Reasons and Hell is for Heroes are two such artists who take their cues from this band.

The band released two widely-acclaimed albums in Slip and Manic Compression before disbanding in 1995. In 1997, Quicksand reunited, and embarked on a successful tour in 1998 with The Deftones. Towards the end of the year they entered the studio to begin work on a follow-up to Manic Compression, but tensions within the band caused them to split up for good.

Walter went on to form Rival Schools.

2) Quicksand were an obscure Welsh psychedelic and progressive rock band active in the early 1970s. The members were Robert Collins, Jimmy Davies, Phil Davies and Anthony Stone. They released two singles, Passing By/Cobblestones (Carnaby CNS 4015) in 1970 and Time To Live/Empty Street, Empty Heart (Dawn DNS 1046) in 1973. Their only album, Home Is Where I Belong (Dawn DNLS 3056), was released in 1974.

3) Quicksand (Zivo blato) is a Croatian heavy metal band. It was founded in Split in 1998 by folk/rock singer Sinisa Vuco. It's a trio consisting of Sinisa Vuco - which takes the stage name Vasilije Mitu (guitar/vocals), Veseli Sir (bass), and Mala Planina (drums). "Mala Planina" is actually Mirjan Jovanovic - "Toso", a famous drummer from Split.
