First off Texas Flood is not a derivation of Red House. Most blues songs have the same basic chord pattern and a rhythm that can be a shuffle, boogie woogie, etc. Red House and Texas Flood are both I-IV-V blues progressions which means you play the I IV and V chord which in the key of E would be E A and B. You can play a I-IV-V in any key you wish to. SRV played Texas Flood in G, which means the chords are G C D. In Red House the chords are B E G. These two songs are also 12 bar blues which means this: you typically play the first chord for for 4 bars, the second for 4 bars, and the third one 4 bars. Texas Flood is also 12 bar. That's why you get the same vibe out of both songs and they sound similar. Get in to blues real big and you will see most of them sound similar, differentiated mainly by the vocals and the individual player's licks. Anyway, the song is about Jimi's girlfriend Betty Jean and how when he came back from the Army she didn't live there anymore. The song strays from reality in the fact that he wasn't blue over her as he didn't want her anymore, and she didn't live in a red house, she lived in a brown house. Red House was one of the first songs Jimi wrote but even then he knew that a song about a red house would sound better and be more popular than brown.
