Question:
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.
Dinosaur recorded much of their second album You're Living All Over Me with Sonic Youth engineer Wharton Tiers in New York. During the recording process, tension emerged between Mascis and Murph because Mascis had very specific ideas for the drum parts. Barlow recalled, "J controlled Murph's every drumbeat...And Murph could not handle that. Murph wanted to kill J for the longest time." Gerard Cosloy was excited by the completed album, but was devastated when Mascis told him the band was going to release it on California-based SST Records. Mascis was reluctant to sign a two-album deal with Homestead, but Cosloy felt betrayed, "There was no way I couldn't take it personally." After the album's completion Mascis moved to New York, leaving the rest of the band feeling alienated. You're Living All Over Me was released in 1987; early copies of the record in the Boston area were packaged with the Weed Forestin' tape, the first release by Barlow's side project Sebadoh. The album received much more attention in the indie-rock community than the debut. While the previous record had featured different musical styles for each song, You're Living All Over Me found the band's various disparate influences merging into each individual song. Although the hardcore punk influences were noticeably more muted than on Dinosaur, the overall sound was much more powerful, with the instruments often recorded very loud and with considerable distortion. While Mascis's guitar, alternating between Black Sabbath-like riffs, squalling solos, dissonant noise-rock and occasional quiet passages, was the main attraction, Barlow's bass, melodic, highly distorted and often playing thick two-note chords, competed for attention. Meanwhile, Murph played the Mascis-composed drum parts in a very heavy and powerful fashion, resulting in a version of the power trio format. Mascis did most of the lead singing, in a detached drawl that presented a contrast with the extreme music. The songs were highly melodic, albeit with odd song structures that avoided the typical verse-chorus-verse patterns of most rock and pop songs. Barlow also composed two songs: the hardcore-influenced "Lose" and an acoustic sonic collage entitled "Poledo" that anticipated his work with Sebadoh. Immediately following the release of You're Living All Over Me, supergroup The Dinosaurs (featuring ex-members of Country Joe and the Fish, Quicksilver Messenger Service, Hot Tuna, Grateful Dead and Jefferson Airplane) sued them over the use of the name, prompting the addition of "Jr."

Question:
William Patrick Corgan Jr. (born March 17, 1967) is an American musician, songwriter, producer, poet, and professional wrestling magnate. He is best known as the lead singer, primary songwriter, guitarist, and sole permanent member of The Smashing Pumpkins. Formed by Corgan and guitarist James Iha in Chicago, Illinois, in 1988, the band quickly gained steam with the addition of bassist D'arcy Wretzky and drummer Jimmy Chamberlin. Strong album sales and large-scale tours propelled the band's increasing fame in the 1990s until their break-up in 2000.
William Patrick Corgan Jr. was born at Columbus Hospital in Chicago's Lincoln Park neighborhood on March 17, 1967 as the oldest son of William Corgan Sr., a blues/rock guitarist, and Martha Louise Maes Corgan Lutz. He was raised Catholic. His parents had one more son, Ricky, before divorcing in 1970. His father was soon remarried to a flight attendant, and Corgan and his brother went to live with them in Glendale Heights, Illinois. During this time, Corgan alleges he was subject to much physical and emotional abuse by his stepmother. Corgan also developed a protective bond with his younger paternal half-brother, who had special needs as a child. When Corgan's father and stepmother separated, all three boys would live alone with the stepmother, with both of Corgan's birth parents living separately within an hour's drive. Corgan, who grew much faster than his fellow students, was a strong athlete in elementary school. In addition to being a member of his Marquardt Middle School baseball team, he collected baseball cards (amassing over 10,000) and listened to every Chicago Cubs game. However, by the time he began attending Glenbard North High School in Carol Stream, Illinois, he had become only an average athlete. He decided to start playing guitar when he went over to a friend's house and saw his friend's Flying V. Corgan gave his savings to his father, who bought him a used Les Paul knock-off. Corgan, Sr. steered his son stylistically, encouraging him to listen to Jeff Beck and Jimi Hendrix, but offered little other support, and the younger Corgan taught himself to play the instrument. His musical interests in his formative years included hard rock like Guts-era John Cale, heavy metal pioneers Black Sabbath, and mainstream rock like Queen, Boston, ELO, Rush, and Cheap Trick. In high school, Corgan discovered alternative rock through Bauhaus and The Cure. Corgan performed in a string of bands in high school, and graduated as an honor student. Despite grant and scholarship offers from a number of schools, and a tuition fund left by his grandmother, Corgan decided to pursue music full-time. Not finding the Chicago music scene to his liking, he moved from Chicago to St. Petersburg, Florida in 1985 with his first major band, The Marked (so named for the conspicuous birthmarks of both Corgan and drummer Ron Roesing). Not finding success in St. Petersburg, the band dissolved; Corgan moved back to Chicago to live with his father. Corgan performed with Wayne Static in Static's first band Deep Blue Dream, in 1987/88.
