Successful and Sumptuous.
In the mid - 1990s there was a strong interest in indie music on the part of corporations. This happened after Nirvana recorded its debut album Bleach, which became mega-popular. Since successful and independent bands like Oasis and Blur were imitated by many musicians, the tag "indie" was attached to anyone whose sound resembled familiar tunes. And since the whole independent music movement-Paris-began and accumulated in Britain, experimental alternative rock music released in England was mostly tagged with the "indie" label.
The four main styles
It is difficult to determine exactly which musicians belong to this genre, as many change their usual sound and experiment within their styles. However, it is generally accepted that indie is necessarily rocked - mellow and unusual. It breaks down into four main styles: indie rock, indie pop, indie folk, and indie electronica.
Indie rock. Soft rock mixed with Brit-pop, and it's probably the most familiar sound for indie bands. Independent rock has motifs of shoegaze, blues rock, and garage rock. And also this kind of rock has absorbed many other styles, so it's hard to predict - you can't buy an indie album and know exactly what it's going to sound like. It could be punk and post-punk, retro rock and lo-fi.
