Dinosaur Jr. is an American rock band formed in Amherst, Massachusetts, in 1984, originally simply called Dinosaur until legal issues forced a change in name. The band was founded by J Mascis (guitar, vocals, primary songwriter), Lou Barlow (bass, vocals), and Murph (drums). After three albums on independent labels earned the band a reputation as one of the formative influences on American alternative rock, creative tension led to Mascis firing Barlow, who later formed Sebadoh and Folk Implosion. His replacement, Mike Johnson came aboard for three major-label albums.

Mascis and Barlow played together, on drums and guitar respectively, in the hardcore punk band Deep Wound, formed in 1982 while the pair were attending high school in western Massachusetts. After high school, they began exploring slower yet still aggressive music such as Black Sabbath, the Replacements, and Neil Young. Mascis' college friend Gerard Cosloy introduced him to psychedelic-influenced pop bands like Dream Syndicate, which Mascis in turn showed to Barlow. Barlow explained, "We loved speed metal...and we loved wimpy-jangly stuff".  Deep Wound broke up in mid-1984. Cosloy had dropped out of the University of Massachusetts Amherst to focus on running his independent record label, Homestead Records, and promised Mascis that if he were to make a record Homestead would release it. Mascis wrote a number of songs by himself and showed them to Barlow, to whom he offered the bassist position. Barlow said the songs "were fucking brilliant...They were so far beyond. I was still into two-chord songs and basic stuff like 'I'm so sad.' While I was really into my own little tragedy, J was operating in this whole other panorama." Mascis enlisted vocalist Charlie Nakajima, also formerly of Deep Wound, and drummer Emmett Patrick Murphy, otherwise known as Murph, to complete the band. Mascis explained the concept behind the group as "ear-bleeding country".  The band was initially named Mogo, and played their first show on University of Massachusetts Amherst campus in the first week of September 1984. However, Nakajima used the performance to launch an extended anti-police tirade. Mascis was so appalled by Nakajima's behavior at the show that he disbanded the group the next day. A few days later Mascis invited Barlow and Murph to form a new band without telling Nakajima. "I was kind of too wimpy to kick him out, exactly," Mascis later admitted. "Communicating with people has been a constant problem in the band." The trio named themselves Dinosaur, and Mascis and Barlow took over lead-vocal duties. CANNOTANSWER

Dinosaur Jr. är ett amerikanskt rockband bildat i Amherst, Massachusetts, 1984, ursprungligen helt enkelt kallat Dinosaur tills juridiska frågor tvingade fram en namnändring. Bandet grundades av J Mascis (gitarr, sång, primär låtskrivare), Lou Barlow (bas, sång), och Murph (trummor). Efter tre album på oberoende bolag förskaffade bandet ett rykte som en av de formativa influenserna på amerikansk alternativ rock, kreativ spänning ledde till att Mascis sparkade Barlow, som senare bildade Sebadoh och Folk Implosion. Hans ersättare, Mike Johnson kom ombord för tre stora skivalbum. Mascis och Barlow spelade tillsammans, på trummor respektive gitarr, i hardcorepunkbandet Deep Wound, bildat 1982 medan paret gick i high school i västra Massachusetts. Efter gymnasiet började de utforska långsammare men ändå aggressiv musik som Black Sabbath, the Replacements och Neil Young. Mascis collegevän Gerard Cosloy introducerade honom för psykedelisk-influerade popband som Dream Syndicate, vilket Mascis i sin tur visade för Barlow. Barlow förklarade, "Vi älskade speed metal... och vi älskade mesiga-jangly grejer". Deep Wound splittrades i mitten av 1984. Cosloy hade hoppat av University of Massachusetts Amherst för att fokusera på att driva sitt oberoende skivbolag, Homestead Records, och lovade Mascis att om han skulle göra en skiva skulle Homestead släppa den. Mascis skrev ett antal låtar av sig själv och visade dem för Barlow, som han erbjöd basistpositionen till. Barlow sa att låtarna "var jävligt lysande ... de var så långt bortom. Jag var fortfarande inne på två-chord låtar och grundläggande saker som 'Jag är så ledsen.' Medan jag verkligen var inne på min egen lilla tragedi, var J verksam i hela detta andra panorama." Mascis värvade vokalisten Charlie Nakajima, även tidigare av Deep Wound, och trummisen Emmett Patrick Murphy, annars känd som Murph, för att färdigställa bandet. Mascis förklarade begreppet bakom gruppen som "öronblödande land". Bandet hette till en början Mogo, och spelade sin första show på University of Massachusetts Amherst campus första veckan i september 1984. Nakajima använde dock prestandan för att lansera en förlängd antipolistirad. Mascis blev så bestört över Nakajimas beteende på showen att han upplöste gruppen dagen därpå. Några dagar senare bjöd Mascis in Barlow och Murph att bilda ett nytt band utan att berätta för Nakajima. "Jag var lite för mesig för att sparka ut honom, exakt", erkände Mascis senare. "Att kommunicera med folk har varit ett konstant problem i bandet." Trion döpte sig till Dinosaur, och Mascis och Barlow tog över bly-vokalsysslor.
